7. Folding Test

This test verifies the Simple Language folding builder, implemented in the Folding Builder section of the Custom Language Support Tutorial, works as expected.

Define Test Data

Create a file FoldingTestData.java in the testData directory. This java file contains markup instructions for three different cases of code folding.

public class Test {
    public static void main(String[] args)<fold text=' { '> {
        </fold>System.out.println("<fold text='https://en.wikipedia.org/'>simple:website</fold>");<fold text=' }'>
    }</fold>
    public static void main1(String[] args)<fold text=' { '> {
        </fold>System.out.println("<fold text='This is the value that could be looked up with the key \"key with spaces\".'>simple:key with spaces</fold>");<fold text=' }'>
    }</fold>
    public static void main2(String[] args)<fold text=' { '> {
        </fold>System.out.println("<fold text='Welcome to \n          Wikipedia!'>simple:message</fold>");<fold text=' }'>
    }</fold>
}

Define a Test

Add the testFolding() method to the SimpleCodeInsightTest class previously defined. This test method reuses the DefaultTestData.simple properties file.

  public void testFolding() {
    myFixture.configureByFile("DefaultTestData.simple");
    myFixture.testFolding(getTestDataPath() + "/FoldingTestData.java");
  }

Run the Test

Run the test and make sure it's green.
