JUnitParams

Parameterised tests that don't suck

Example

@RunWith(JUnitParamsRunner.class)
public class PersonTest {

  @Test
  @Parameters({"17, false", 
               "22, true" })
  public void personIsAdult(int age, boolean valid) throws Exception {
    assertThat(new Person(age).isAdult(), is(valid));
  }
  
}

About

JUnitParams project adds a new runner to JUnit and provides much easier and readable parametrised tests for JUnit >= 4.12.

Main differences to standard JUnit Parametrised runner:

• more explicit - params are in test method params, not class fields
• less code - you don't need a constructor to set up parameters
• you can mix parametrised with non-parametrised methods in one class
• params can be passed as a CSV string or from a parameters provider class
• parameters provider class can have as many parameters providing methods as you want, so that you can group different cases
• you can have a test method that provides parameters (no external classes or statics anymore)
• you can see actual parameter values in your IDE (in JUnit's Parametrised it's only consecutive numbers of parameters):

Quickstart

JUnitParams is available as Maven artifact:

<dependency>
  <groupId>pl.pragmatists</groupId>
  <artifactId>JUnitParams</artifactId>
  <version>1.1.1</version>
  <scope>test</scope>
</dependency>

To use JUnitParams in a Gradle build add this to your dependencies:

testCompile 'pl.pragmatists:JUnitParams:1.1.1'

If you want to see just one simple test class with all main ways to use JUnitParams see here: https://github.com/Pragmatists/junitparams/tree/master/src/test/java/junitparams/usage
