8. Find Usages Test

Define the Test Data

Create the FindUsagesTestData.simple file in the testData directory.

# You are reading the ".properties" entry. ! The exclamation mark can also mark text as comments. website = 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 <caret>key\ with\ spaces = This is the value that could be looked up with the key "key with spaces". # Unicode tab : \u0009

Create the test file, which contains one embedded Simple Language prefix and key.

public class Test { public static void main(String[] args) { System.out.println("simple:key with spaces"); } }

Define a Test Method

Add the testFindUsages() method to the SimpleCodeInsightTest class previously defined. This test verifies the find usage functionality will identify the "key with spaces".

public void testFindUsages() { Collection<UsageInfo> usageInfos = myFixture.testFindUsages("FindUsagesTestData.simple", ""); assertEquals(1, usageInfos.size()); }

Run the Test

Run the test and make sure it's successful.

Running tests

  1. Open the Gradle Tool Window.

  2. Select the simple_language_plugin node. You may need to reimport it as a Gradle project.

  3. Drill down under simple_language_plugin to Tasks, verification, test task.

  4. 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:

  1. In the Gradle Tool Window, drill down under simple_language_plugin to Tasks, build, clean task.

  2. Run the clean task, which deletes the simple_language_plugin/build directory.

  3. Restart the test.
