8. Find Usages Test

This test ensures the find usages provider, implemented in the Find Usages Provider section of the Custom Language Support Tutorial, works correctly.

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 green.
