Best way to automagically migrate tests from JUnit 3 to JUnit 4?
There's actually an alternative to the @Test(expected=Xyz.class)
in JUnit 4.7 using Rule
and ExpectedException
In your test case you declare an ExpectedException
annotated with @Rule
, and assign it a default value of ExpectedException.none()
. Then in your test that expects an exception you replace the value with the actual expected value. The advantage of this is that without using the ugly try/catch method, you can further specify what the message within the exception was
@Rule public ExpectedException thrown= ExpectedException.none();
@Test
public void myTest() {
thrown.expect( Exception.class );
thrown.expectMessage("Init Gold must be >= 0");
rodgers = new Pirate("Dread Pirate Rodgers" , -100);
}
Using this method, you might be able to test for the message in the generic exception to be something specific.
ADDITION
Another advantage of using ExpectedException
is that you can more precisely scope the exception within the context of the test case. If you are only using @Test(expected=Xyz.class)
annotation on the test, then the Xyz exception can be thrown anywhere in the test code -- including any test setup or pre-asserts within the test method. This can lead to a false positive.
Using ExpectedException, you can defer specifying the thrown.expect(Xyz.class)
until after any setup and pre-asserts, just prior to actually invoking the method under test. Thus, you more accurately scope the exception to be thrown by the actual method invocation rather than any of the test fixture itself.
JUnit 5 NOTE:
JUnit 5 JUnit Jupiter has removed @Test(expected=...)
, @Rule
and ExpectedException
altogether. They are replaced with the new assertThrows()
, which requires the use of Java 8 and lambda syntax. ExpectedException
is still available for use in JUnit 5 through JUnit Vintage. Also JUnit Jupiter will also continue to support JUnit 4 ExpectedException
through use of the junit-jupiter-migrationsupport module, but only if you add an additional class-level annotation of @EnableRuleMigrationSupport
.

There are various CI/CD tools such as CircleCI, TeamCity, Bamboo, Jenkins, GitLab, Travis CI, GoCD, etc., that help companies streamline their development process and ensure high-quality applications. If we talk about the top CI/CD tools in the market, Jenkins is still one of the most popular, stable, and widely used open-source CI/CD tools for building and automating continuous integration, delivery, and deployment pipelines smoothly and effortlessly.

The Selenium automation framework supports many programming languages such as Python, PHP, Perl, Java, C#, and Ruby. But if you are looking for a server-side programming language for automation testing, Selenium WebDriver with PHP is the ideal combination.
While working on a project for test automation, you’d require all the Selenium dependencies associated with it. Usually these dependencies are downloaded and upgraded manually throughout the project lifecycle, but as the project gets bigger, managing dependencies can be quite challenging. This is why you need build automation tools such as Maven to handle them automatically.
LambdaTest also has a detailed JUnit tutorial explaining its features, importance, advanced use cases, best practices, and more to help you get started with running your automation testing scripts.
Here are the detailed JUnit testing chapters to help you get started:
You can also check out our JUnit certification if you wish to take your career in Selenium automation testing with JUnit to the next level.
