6. Rename Test

Define Input Test Data

Create the RenameTestData.simple properties file in the testData directory.

# You are reading the ".properties" entry.
! The exclamation mark can also mark text as comments.
website = https://en.wikipedia.org/

language = English
# The backslash below tells the application to continue reading
# the value onto the next line.
message = Welcome to \
          Wikipedia!
# Add spaces to the key
key\ with\ spaces = This is the value that could be looked up with the key "key with spaces".
# Unicode
tab : \u0009

Create the file RenameTestData.java in the testData directory. This file contains one Simple Language reference embedded in Java, with the caret position placed just after a Simple Language key.

public class Test {
  public static void main(String[] args) {
    System.out.println("simple:website<caret>");
  }
}

Create Output Test Data

Create the RenameTestDataAfter.simple file in the testData directory. This file contains the expected outcome of the test. Note the website = in RenameTestData.simple should be renamed to websiteUrl = by the test.

# You are reading the ".properties" entry.
! The exclamation mark can also mark text as comments.
websiteUrl = https://en.wikipedia.org/

language = English
# The backslash below tells the application to continue reading
# the value onto the next line.
message = Welcome to \
          Wikipedia!
# Add spaces to the key
key\ with\ spaces = This is the value that could be looked up with the key "key with spaces".
# Unicode
tab : \u0009

Define a Test Method

Add the testRename() method to the SimpleCodeInsightTest class previously defined.

Again, this method configures the test fixture by using the test files.
The fixture then renames the Simple Language element at the caret in RenameTestData.java.
It then compares the input and output files, ignoring whitespace.

  public void testRename() {
    myFixture.configureByFiles("RenameTestData.java", "RenameTestData.simple");
    myFixture.renameElementAtCaret("websiteUrl");
    myFixture.checkResultByFile("RenameTestData.simple", "RenameTestDataAfter.simple", false);
  }

Run the Test

Run the test and make sure it's successful.

Running tests

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/build/test-results/test directory.

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.
