9. Commenter Test
Tested Functionality: 18. Commenter
tip
This page is part of multistep Testing a Custom Language Plugin tutorial.
Add the testCommenter() method to the SimpleCodeInsightTest class previously defined. This test constructs a Simple Language properties file containing one line, with the virtual caret positioned at the beginning of the line. The test calls the commenter to insert a comment character at the caret, then verifies the results. It again calls the line comment action to remove the comment character and verifies the results.
public void testCommenter() {
myFixture.configureByText(SimpleFileType.INSTANCE, "<caret>website = https://en.wikipedia.org/");
CommentByLineCommentAction commentAction = new CommentByLineCommentAction();
commentAction.actionPerformedImpl(getProject(), myFixture.getEditor());
myFixture.checkResult("#website = https://en.wikipedia.org/");
commentAction.actionPerformedImpl(getProject(), myFixture.getEditor());
myFixture.checkResult("website = https://en.wikipedia.org/");
}Run the test and make sure it's successful.
Open the Gradle Tool Window.
Select the simple_language_plugin node. You may need to reimport it as a Gradle project.
Drill down under simple_language_plugin to Tasks, verification, test task.
Run the test task.
The results are displayed in the Run Tool Window, and also written to the simple_language_plugin
If the Run Tool Window displays the error Test events were not received, do the following:
In the Gradle Tool Window, drill down under simple_language_plugin to Tasks, build, clean task.
Run the clean task, which deletes the simple_language_plugin/build directory.
Restart the test.
