Gwen
Gwen is a simple library that allows writing acceptance tests in a Given-When-Then syntax.
Using Gwen, we can transform a very verbose and implementation specific test like this:
public void testNotGonnaTellYou() {
final Instrumentation instrumentation = getInstrumentation();
final Context targetContext = instrumentation.getTargetContext();
File cacheDir = targetContext.getCacheDir();
try {
File file1 = File.createTempFile("file1", "txt", cacheDir);
File file2 = File.createTempFile("file2", "txt", cacheDir);
}
catch (IOException e) {
e.printStackTrace();
Assert.fail("Failed to create files " + e.getMessage());
}
Intent intent = new Intent(targetContext, DirectoryBrowserActivity.class);
intent.setData(Uri.parse(cacheDir.getAbsolutePath()));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
targetContext.startActivity(intent);
final Solo solo = new Solo(instrumentation);
final boolean file1Displayed = solo.searchText("file1.txt");
final boolean file2Displayed = solo.searchText("file2.txt");
if (!file1Displayed || !file2Displayed) {
Assert.fail("Activity did not display files");
}
}
into a readable, reusable, extensible and maintainable test like this:
public void testDisplaysDirectoryContents() {
given(directory).contains(SOME_FILES);
when(user).isViewing(directory);
then(user).canSee(THESE_FILES);
}
