TestNG plugin

This plugin is a TestNG runner for Play Framework 2.2.0. It using the TestNG sbt interface by jmhofer to run TestNG Test suites, and adds Helpers. Example can be found in the sample folder.

Usage

instalation

Plugin

Add the plugin in your project/plugins.sbt file.

addSbtPlugin("com.linkedin" % "play-plugins-testng" % "2.2.3")

Add the following to your project's build.sbt file:

import com.linkedin.plugin.NGPlugin._
ngSettings

Helpers

Add the dependency in your project/Build.scala file.

val appDependencies = Seq(
 "com.linkedin" %% "play-testng-helpers" % "2.2.3"
)

Test classes must extend NGTests to use the helpers. Use com.linkedin.plugin.j.* in Java code and com.linkedin.plugin.s.* from Scala code.

Annotations

@WithFakeApplication

@WithFakeApplication runs the test in the context of a Play application.

It's equivalent to:

running(fakeApplication(), new Runnable() {
  public void run() {
    // Your
  }
});

This Annotation can be used on Test methods and test classes. When it's used on a class, a FakeApplication will be started at the beginning of each test, and stop when the test finishes.

@WithFakeApplication
public class AllWithFakeApp extends NGTests {
 @Test
 public void aFastTest() {
    String f = play.Play.application().configuration().getString("test.loutre");
    if(!f.equals("oink"))
       throw new RuntimeException("Assertion failed");
 }
}

public class SimpleTest extends NGTests {
 @Test
 @WithFakeApplication
 public void aFailingTest() {
   String f = play.Play.application().configuration().getString("test.fakeconf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }
}

@Conf

You can change the application configuration for testing purpose using the @Conf annotation:

public class SimpleTest extends NGTests {
 
 @Test
 public void aFastTest() {
    System.out.println("Fast test");
 }
 
 @Test
 @WithFakeApplication
 @Conf(key="test.fakeconf", value="fake") // wil override the application.conf value for "test.fakeconf"
 public void aFailingTest() {
   String f = play.Play.application().configuration().getString("test.fakeconf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }
}

Alternatively, if you need to change multiple configuration entries, you can wrap those @Conf into a @Confs:

public class SimpleTest extends NGTests {
 
 @Test
 public void aFastTest() {
    System.out.println("Fast test");
 }
 
 @Test
 @WithFakeApplication
 @Confs({
    @Conf(key="test.fakeconf", value="fake"),
    @Conf(key="test.loutre", value="oink")
 })
 public void aFailingTest() {
   String f = play.Play.application().configuration().getString("test.fakeconf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }
}

The @Conf and @Confs annotation also work on test Classes. When used on classes, the new configuration will be used for every test in this class:

@WithFakeApplication
@Conf(key="test.fakeconf", value="fake")
public class AllWithFakeApp extends NGTests {
 @Test
 public void anotherFastTest() {
   String f = play.Play.application().configuration().getString("test.fakeconf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }
}

Declaration on classes and methods can be mixed:

@WithFakeApplication
@Confs({
  @Conf(key="test.fakeconf", value="fake"),
  @Conf(key="test.anotherConf", value="fake")
})
public class AllWithFakeApp extends NGTests {
 
 @Test
 public void testAnotherConf() {
   String f = play.Play.application().configuration().getString("test.anotherConf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }
 
 @Test
 @Conf(key="test.singleConf", value="fake")
 public void testASingleConf() {
   String f = play.Play.application().configuration().getString("test.singleConf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }
 
}

Note: @Confs and @Conf will be ignored if tests (class or method) are not annotated with @WithFakeApplication.

Replacing plugins: @WithPlugins

Using @WithPlugins, you can replace or add plugin to the FakeApplication ran for your test.

 @Test
 @WithFakeApplication
 @WithPlugins({"plugins.DummyPlugin"})
 public void aFailingTest() {
   String f = play.Play.application().configuration().getString("test.fakeconf");
   if(!f.equals("fake"))
     throw new RuntimeException("Assertion failed");
 }

Like @WithFakeApplication, @WithPlugins can be used on classes.
