JUnit 5

In this tutorial, you will learn how to set up JUnit for your projects, create tests, and run them to see if your code is operating correctly. It contains just the basic steps to get you started.

If you want to know more about JUnit, refer to the official documentation. To learn more about testing features of IntelliJ IDEA, refer to other topics in this section.

You can choose to follow error dependency jupiter ubuntu tutorial using either Maven or Gradle.

Create a project

  1. From the main menu, select .

  2. Select New Project. Specify the name for the project, for example.

  3. Select Maven as a build tool. In Language, select Java.

  4. From the JDK list, select the JDK that you want to use in your project.

    If the JDK is installed on your computer, but not defined in the IDE, select Add JDK and specify the path to the JDK home directory.

    If you don't have the necessary JDK on your computer, select Download JDK.

  5. Click Create.

For more information on working with Maven projects, refer to Maven.

Add dependencies

For our project to use JUnit features, we need to add JUnit as a dependency.

  1. Open pom.xml in the root directory of your project.

    To quickly navigate to a file, press and enter its name.

  2. In pom.xml, pressselect Add dependency.

  3. In the tool window that opens, type in the search field.

    Locate the necessary dependency in the search results and click Add next to it.

  4. Now we need to apply the changes in the build script. Press or click Load Maven Changes in the notification that appears in the top-right corner of the editor.

    The Load Maven Changes button

The procedure above shows the 'manual' way error dependency jupiter ubuntu that you know what happens behind the scenes and where you set up the testing framework. However, error dependency jupiter ubuntu, if you just start writing tests, IntelliJ IDEA will automatically detect if the dependency is missing and prompt you to add it.

Create a project

  1. From the main menu, select .

  2. Select New Project. Specify the name for the project, for example.

  3. Select Gradle as a build tool. In Language, select Java.

  4. From the JDK list, select the JDK that you want to use in your project.

    If the JDK is installed on your computer, but not defined in the IDE, select Add JDK and specify the path to the JDK home directory.

    If you don't have the necessary JDK on your computer, select Download JDK.

  5. Click Create.

For more information on working with Gradle projects, refer to Gradle.

Add dependencies

For our project to use JUnit features, we need to add JUnit as a dependency.

  1. Open build.gradle in the root directory of your project.

    To quickly navigate to a file, error dependency jupiter ubuntu, press and enter its name.

  2. In build.gradle, pressselect Add dependency.

  3. In the tool window that opens, type error dependency jupiter ubuntu in the search field.

    Locate the necessary dependency in the search results and click Add next to it.

  4. Now we need to apply the changes in the build script. Press or click Load Gradle Changes in the notification that appears in the top-right corner of the editor.

    The Load Gradle Changes button

The procedure above shows the 'manual' way so that you know what happens behind the scenes and where you set up the testing framework. However, if you just start writing tests, IntelliJ IDEA will automatically detect if the dependency is missing and prompt you to add it.

Write application code

Let's add some code that we'll be testing.

  1. In the Project tool windowgo to src/main/java and create a Java file called .

  2. Paste the following code in the file:

    import java.util.stream.DoubleStream; public class Calculator { static double add(double. operands) { return DoubleStream.of(operands) .sum(); } static double multiply(double. operands) { return DoubleStream.of(operands) .reduce(1, (a, b) -> a * b); } }

Create tests

Now let's create a test. A test is a piece of code whose function is to check if another piece of code is operating correctly, error dependency jupiter ubuntu. In canon mp220 5100 error to do the check, it calls the tested method and compares the result with the predefined expected result. An expected result can be, for example, a specific return value or an exception.

  1. Place the caret at the class declaration and press. Ptlib linux/videodev.h error, right-click it and select Show Context Actions. From the menu, select Create Test.

    The code of the class that we are going to test
  2. Select the two class methods that we are going to test.

    The Create Test dialog
  3. The editor takes you to the newly created test class, error dependency jupiter ubuntu. Modify the test as follows:

    @Test @DisplayName("Add two numbers") void add() { assertEquals(4, Calculator.add(2, 2)); }

    This simple test will check if our method correctly adds 2 and 2, error dependency jupiter ubuntu. The annotation specifies a more convenient and informative name for the test.

  4. Now what if you want to add multiple assertions in a single test and execute all of them regardless of whether some of them fail? Let's do it for the method:

    @Test @DisplayName("Multiply two numbers") void multiply() { assertAll(() -> assertEquals(4, error dependency jupiter ubuntu, Calculator.multiply(2, 2)), () -> assertEquals(-4, Calculator.multiply(2, error dependency jupiter ubuntu, -2)), () -> assertEquals(4, Calculator.multiply(-2, -2)), error dependency jupiter ubuntu, () -> assertEquals(0, Calculator.multiply(1, 0))); }

    The method takes a series of assertions in form of lambda expressions and ensures all of them are checked. This is more convenient than having multiple single assertions because you will always see a granular result rather than the result of the entire test.

To navigate between the test and the code being tested, use the shortcut.

Run tests and view their results

After we have set up the code for the testing, we can run the tests and find out if the tested methods are working correctly.

  • To run an individual test, click App run configurations test state run in the gutter and select Run.

    The popup that appears after clicking on the Run icon in the gutter
  • To run all tests in a test class, click App run configurations test state run against the test class declaration and select Run.

You can view test results in the Run tool window.

The results of the tests shown in the Run tool window

IntelliJ IDEA hides passed tests by default. To see them, make sure the Show Passed option is enabled in the Run tool window.

Upgrade to Selenium 4

Are you still using Selenium 3? This guide will help you upgrade to the latest release!

Upgrading to Selenium 4 should be a painless process if you are using one of the officially supported languages (Ruby, JavaScript, C#, Python, and Java). There might be some cases where a few issues can happen, and this guide will help you to sort them out. We will go through the steps to upgrade your project dependencies and understand the major deprecations and changes the version upgrade brings.

These are the steps we will follow to upgrade to Selenium 4:

  • Preparing our test code
  • Upgrading dependencies
  • Potential errors and deprecation messages

Note: while Selenium 3.x versions were being developed, support for the W3C WebDriver standard was implemented. Both this new protocol and the legacy JSON Wire Protocol were supported. Around version 3.11, Selenium code became compliant with the level W3C 1 specification. The W3C compliant code in the latest version of Selenium 3 will work as expected in Selenium 4.

Preparing our test code

Selenium 4 removes support for the legacy protocol and uses the W3C WebDriver standard by default under the hood. For most things, this implementation will not affect end users. The major exceptions are and the class.

Capabilities

If the test capabilities error dependency jupiter ubuntu not structured to be W3C compliant, may cause a session to not be started, error dependency jupiter ubuntu. Here is the list of W3C WebDriver standard capabilities:

  • (replaces )
  • (replaces )

An up-to-date list of standard capabilities can be found at W3C WebDriver.

Any capability that is not contained in the list above, error dependency jupiter ubuntu to include a vendor prefix, error dependency jupiter ubuntu. This applies to browser specific capabilities as well as cloud vendor specific capabilities. For example, if your cloud vendor uses and capabilities for your tests, you need to wrap them in a block (check with your cloud vendor for the appropriate prefix).

Find element(s) utility methods in Java

The utility methods to find elements in the Java bindings ( interfaces) have been removed as they were meant for internal use only. The following code samples explain this better.

Upgrading dependencies

Check the subsections below to install Selenium 4 and have your project dependencies upgraded.

Java

The process of upgrading Selenium depends on which build tool is being used. We will cover the most common ones for Java, which are Maven and Gradle. The minimum Java version required is still 8.

Maven

After making the change, you could execute on the same directory where the file is.

Gradle

After making the change, you could execute on the same directory where the file is.

To check all the Java releases, you can head to MVNRepository.

C#

The place to get updates for Selenium 4 in C# is NuGet. Under the package you can get the instructions to update to the latest version, error dependency jupiter ubuntu. Inside of Visual Studio, through the NuGet Package Manager you can execute:

Python

The most important change to use Python is the minimum required version. Selenium 4 will require a minimum Python 3.7 or higher. More details can be found at the Python Package Index. To upgrade from the command line, you can execute:

Ruby

The update details for Selenium 4 can be seen at the selenium-webdriver gem in RubyGems. To install the latest version, you can execute:

To add it to your Gemfile:

JavaScript

The selenium-webdriver package can be found at the Node package manager, npmjs. Selenium 4 can be found here. To install it, you could either execute:

Or, error dependency jupiter ubuntu, update your package.json and run:

Potential errors and deprecation messages

Here is a set of code examples that will help to overcome the deprecation messages you might encounter after upgrading to Selenium 4.

Java

Waits and Timeout

The parameters received in Timeout have switched from expecting to expect .

Waits are also expecting different parameters now. is now expecting a instead of a for timeout in seconds and milliseconds. The and utility methods from have switched from expecting to expect .

Merging capabilities is no longer changing the calling object

It was possible to merge a different set of capabilities into another set, and it was mutating the calling object. Now, the result of the merge operation needs to be assigned.

As a result, the object was getting modified.

The result of the call needs to be assigned to an object.

Firefox Legacy

Before GeckoDriver was around, the Selenium project had a driver implementation to automate Firefox (version <48). However, error dependency jupiter ubuntu, this implementation is not needed anymore as it does not work in recent versions of Firefox. To avoid major issues when upgrading to Selenium 4, the option will be shown as deprecated. The recommendation is to stop using the old implementation and rely only on GeckoDriver. The following code will show the line deprecated after upgrading.

The interface has been around for a long time, however it is getting deprecated in favour of the new interface.

C#

is deprecated

Instead of it, is recommended, error dependency jupiter ubuntu. Here is an example showing this:

Python

In Selenium 4, you’ll need to set the driver’s from a Service object to prevent deprecation warnings. (Or don’t set the path and instead make sure that the driver you need is on the System PATH.)

Summary

We went through the major changes to be taken into consideration when upgrading to Selenium 4. Covering error dependency jupiter ubuntu different aspects to cover when test code is prepared for the upgrade, including suggestions on how to prevent potential issues that can show up when using the new version of Selenium. To finalize, we also covered a set of possible issues that you can bump into after upgrading, and we shared potential fixes for those issues.

4.3.1, error dependency jupiter ubuntu. Maven repositories and dependency resolution

A repository is a collection of libraries and project artifacts stored in a directory structure similar to the Maven coordinates of the project.

During the initial phase of a build Maven validates, if you have the specified version of all required artifact dependencies and Maven plug-ins. If required, it retrieves them from a Maven repository.

If necessary, Maven downloads these artifacts and plug-ins into a local repository. The default local repository is located in the home directory of the user in the .m2/repository folder. If an artifact or a plug-in is available in the local repository, Maven uses it for the build to avoid unnecessary network traffic.

Maven uses a default remote repository location (http://repo1.maven.org/maven2) from which it downloads the core Maven plugins and dependencies. You can configure Maven to use more repositories and replace the default one.

Every project can define dependencies using the unique identifier (GAV) of the library it requires.

During a build, the Maven system tries to resolve the dependencies of the modules which are build. To resolve dependencies, Maven uses the following sources in the given order:

  • Projects which are included in the same Maven run (the so called Maven reactor)

  • Local repository

  • Maven central repository

Maven supports direct and transitive dependencies, error dependency jupiter ubuntu. Direct dependencies are the ones that are explicitly included in the pom file of the project. Transitive dependencies are dependencies required by our direct dependencies.

Maven handles direct and transitive dependencies.

For this, error dependency jupiter ubuntu, you specify in the pom file the external libraries your project depends on using their GAV (groupId, artifactId and version) then Maven downloads them, puts them in your error dependency jupiter ubuntu Maven repository and make them available for the project build. The transitive dependencies of the required libraries are also made available.

The following listing shows a pom file with a dependency to JUnit5.

1This build section is required as starting with version 2.22.0, Maven Surefire and Maven Failsafe provide native support for executing tests on the JUnit Platform.
2This defines dependencies for the software tests (via the scope attribute) to JUnit5 (also known as JUnit Jupiter)

Maven will download the defined dependencies and their transitive dependencies from the Maven central repository and add them to the users local Maven repository, error dependency jupiter ubuntu. If the dependencies are already found in your local repository, Maven will use these and download them again.

You can also define an (external of a Maven repository) location for a library.

1Requires that the library is defined via a system path

You can also define snapshot dependencies. These are libraries which can constantly under development. Maven downloads these snapshots on every build, error dependency jupiter ubuntu, even if a matching version is already available in the local repository.

4.3.2. Excluding transitive dependencies

Sometimes your dependencies have conflicting transitive dependencies. For example library A requires library C in version 1.0.0 and library B requires it in version 1.1.0. To use library C in version 1.0.0 you can exclude C from the dependencies of A.

Lets for example B is the artifactId.

Getting help¶

If you think you’ve encountered a bug in seaborn, please report it on the GitHub issue tracker. To be useful, bug reports must include the following information:

  • A reproducible code example that demonstrates the problem

  • The output that you are seeing (an image of a plot, or the error message)

  • A clear explanation of why you think something is wrong

  • The specific versions of seaborn and matplotlib that you are working with

Bug reports are easiest to address if they can be error dependency jupiter ubuntu using one of the example datasets from the seaborn docs (i.e. with ). Otherwise, it is preferable that your example generate synthetic data to reproduce the problem. If you can only demonstrate the issue with your actual dataset, you will need to share it, ideally as a csv.

If you’ve encountered an error, searching the specific text of the message before opening a new issue can often help you solve the problem quickly and avoid making error dependency jupiter ubuntu duplicate report.

Because matplotlib handles the actual rendering, errors or incorrect outputs may be due to a problem in matplotlib rather than one in seaborn. It can save time if you try to reproduce the issue in an example that uses only matplotlib, so that you can report it in the right place. But it is alright to skip this step if it’s not obvious how to do it.

General support questions are more at home on either stackoverflow or discourse, which have a larger audience of people who will see your post and may be able to offer assistance. StackOverflow is better for specific issues, while discourse is better for more open-ended discussion. Your chance of getting a quick answer will be higher if you include runnable code, a precise statement of what you are hoping to achieve, and a clear explanation of the problems that you have encountered.

  • JUnit 5 Tutorial: Running Unit Tests With Maven

    This blog post describes how we can create a Maven project that can compile and run unit tests which use JUnit 5. After we have finished this blog post, we:

    • Can get the required dependencies with Maven.
    • Understand how we can configure the Maven Surefire Plugin.
    • Know how we can run our unit tests with Maven.

    Let's start by getting the required dependencies.

    Getting the Required Dependencies

    We can get the required dependencies by adding the reservation link error 5.8.2) dependency to the scope. This is an aggregator artifact which simplifies the dependency management because it has the following transitive dependencies:

    • The dependency ( scope) provides the public API for writing tests and extensions.
    • The dependency ( scope) provides support for writing parameterized tests.
    • The dependency ( scope) contains the implementation of the JUnit Jupiter test engine that runs our unit tests. If we add error dependency jupiter ubuntu dependency to our classpath, the Maven Surefire and Failsafe plugins (version 2.22.0 or newer) can run tests which use JUnit 5.

    After we have added the required dependency to our POM file, error dependency jupiter ubuntu, its section looks as follows:

    <dependencies> <dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter</artifactId> <version>5.8.2</version> <scope>test</scope> </dependency> </dependencies>

    After we have declared the required dependencies, we have to configure the Maven Surefire Plugin. Let's find out how we can do it.

    Configuring the Maven Surefire Plugin

    We can run our unit tests by using the Maven Surefire Plugin. Because we want to use its native JUnit 5 support, we have to use the version 2.22.0 (or newer).

    After we have ensured that our unit tests are run by the Maven Surefire Plugin 2.22.2, the section of our POM file looks as follows:

    <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.2</version> </plugin> </plugins> </build>
    There are two things I want to point out:

    First, if we want to use the native JUnit 5 error dependency jupiter ubuntu of the Maven Surefire Plugin, we must ensure that at least one test engine implementation is found from the classpath. That's why error dependency jupiter ubuntu ensured that the dependency is found from the classpath when we configured the dependencies of our Maven build.

    Second, if we use the default configuration of the Maven Surefire Plugin, it runs all test methods found from a test class if the name of the test class:

    • Starts or ends with the string: .
    • Ends with the string: .
    • Ends with the string: .

    Additional Reading:

    We have now created a Maven project that can run unit tests which use JUnit 5. Let's move on and write a simple unit test with JUnit 5.

    Writing a Simple Unit Test

    Before we can write unit tests which use JUnit 5, we have to know these two things:

    • The src/test/java directory contains the source code of our unit tests.
    • The src/test/resources directory contains the resources of our unit tests.

    Let's create a new test class and add an empty test method to the proteus error log class. After we have written our test class, its source code looks as follows:

    import org.junit.jupiter.api.Test; class JUnit5ExampleTest { @Test void justAnExample() { } }

    If you want to get more information about JUnit 5 test classes, you should read this blog post. Also, it's not a good idea to write empty test methods. I use this technique here only because I want to demonstrate that our test method is run by the Maven Surefire Plugin, error dependency jupiter ubuntu.

    Next, we will find out how we can run our unit tests.

    Running Unit Tests With Maven

    We can run our run-time error 429 xp tests with Maven by using the command: mvn clean test. When we run this command at command prompt, we should see that the Maven Surefire Plugin runs our unit tests.

    [INFO] [INFO] --- maven-surefire-plugin:2.22.2:test (default-test) @ running-unit-tests --- [INFO] ------------------------------------------------------- T E S T S ------------------------------------------------------- Running net.petrikainulainen.junit5.JUnit5ExampleTest Tests run: 1, Failures: error dependency jupiter ubuntu, Errors: 0, Skipped: 0, error dependency jupiter ubuntu, Time elapsed: 0.033 sec - in net.petrikainulainen.junit5.JUnit5ExampleTest Results : Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------

    We can now create a Maven project that compiles and runs unit tests which use Error dependency jupiter ubuntu 5. Also, we know how we can run our unit tests with Maven. Let's summarize what we learned from this blog post.

    Summary

    This blog post has taught us six things:

    • The dependency provides error dependency jupiter ubuntu public API that allows us to write tests and extensions which use JUnit 5.
    • The dependency ensures that the Maven Surefire Plugin can run tests which use JUnit 5.
    • The dependency is an aggregator artifact which simplifies the dependency management because it ensures that the required dependencies are found from the classpath.
    • The Maven Surefire Plugin 2.22.0 (or newer) provides native support for JUnit 5.
    • If we want to use the native JUnit 5 support of the Maven Surefire Plugin, we must ensure that at least one test engine implementation is found from the classpath.
    • We can run our unit tests by using the command: mvn clean test.

    P.S. You can get the example application of this blog post from Github.
