Now let's consider that from our unit test, we want to provide a different value. In the next section, we'll see how we can provide, clean, and make sure we restore system property values after our tests complete in a concise and simple manner. This will let JUnit get the correct implementation and thus avoid having a JUnit Test that’s unrooted. However, if we neglect to do this, it could lead to unexpected side-effects in our tests. The solution is basically just to use the correct library. This can sometimes lead to cumbersome setup and tear down code. Care should be taken when working with system properties from our tests, as these properties are JVM-global.įor example, if we set a system property, we should ensure we restore the property to its original value when our test finishes or if a failure occurs. We can also set our own system properties by using the tProperty method. forEach((key, value) -> (key + ": " + value)) Īs we can see, properties include information such as the current user, the current version of the Java runtime, and file path-name separator: java.version: 1.8.0_221

JUnit 5 is the result of JUnit Lambda and its crowdfunding campaign on Indiegogo.

This includes focusing on Java 8 and above, as well as enabling many different styles of testing. We can easily print out the properties: System.getProperties() The goal is to create an up-to-date foundation for developer-side testing on the JVM.

To quickly recap, the Java platform uses a Properties object to provide information about the local system and configuration.
