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()).reformatText(myFixture.getFile(),
ContainerUtil.newArrayList(myFixture.getFile().getTextRange()));
}
}.execute();
myFixture.checkResultByFile("DefaultTestData.simple");
}
5.3. Run the test
Run the test and make sure it's green.
