5. Formatter Test

In this test we will check if the formatter, implemented in the Formatter section of the Custom Language Support Tutorial works as we expect.

5.1. Define test data

Create a file FormatterTestData.simple.

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

5.2. Define a test method

public void testFormatter() {
    myFixture.configureByFiles("FormatterTestData.simple");
    CodeStyleSettingsManager.getSettings(getProject()).SPACE_AROUND_ASSIGNMENT_OPERATORS = true;
    new WriteCommandAction.Simple(getProject()) {
        @Override
        protected void run() throws Throwable {
            CodeStyleManager.getInstance(getProject()).reformat(myFixture.getFile());
        }
    }.execute();
    myFixture.checkResultByFile("DefaultTestData.simple");
}

5.3. Run the test

Run the test and make sure it's green.
