Test Naming Conventions Plugin

Almost each project uses unit tests in its codebase. It is important to have a common pattern of naming all that tests, because otherwise the project and tests itself become a complete mess. It's a quite large discussion about different test naming patterns . test-naming-conventions maven plugin helps to keep following a single common test naming rule across all of your test classes.

Conventions

The only one convention that is supported by this plugin for now is the present tense without subject.

Present tense without subject

The test method name should be a sentence that describes the test case using present tense without subject. For example, if you have a test that tests a User class, then the test method name should start from the verb followed by the any testing conditions. For example:

public class UserTest {
    @Test
    public void createsUser() {
        // correct
    }

    @Test
    public void createsUserWithoutName() {
        // correct
    }

    @Test
    public void removesUser() {
        // correct
    }
}

The next cases will be considered as invalid:

public class UserTest {
    @Test
    public void createUser() {
        // invalid!
    }

    @Test
    public void userIsCreated() {
        // invalid!
    }

    @Test
    public void userIsRemoved() {
        // invalid!
    }
}

How to use

The plugin could be run using several approaches but for both of them you need at least Maven 3.1.+ and Java 8+.

Invoke the plugin directly

In order to use the plugin with the latest version just invoke the next command in the root of your project:

mvn com.github.volodya-lombrozo:test-naming-conventions:check

After that you will see the result of the plugin execution in the console. If you want to use specific (older) version of the plugin, for example 0.1.4, just run the next maven command with specified version:

mvn com.github.volodya-lombrozo:test-naming-conventions:0.1.4:check

Add the plugin to your `pom.xml`

The more convenient way to use the plugin is to add it to your pom.xml file. In order to do that, just add the next snippet to your pom.xml:

<build>
  <plugins>
    <plugin>
      <groupId>com.github.volodya-lombrozo</groupId>
      <artifactId>test-naming-conventions</artifactId>
      <version>0.1.4</version>
      <executions>
        <execution>
          <goals>
            <goal>check</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

The default plugin phase is verify, so you don't need to specify it directly, but if you want to change it, just add the phase to execution section:

<execution>
  <phase>test</phase>
  <goals>
    <goal>check</goal>
  </goals>
</execution>
