|
|
|
|
In this test we will check if the formatter, implemented in the
|
|
[Formatter](formatter.html)
|
|
section of the
|
|
[Custom Language Support Tutorial](cls_tutorial.html)
|
|
works as we expect.
|
|
|
|
### 1. Define test data
|
|
|
|
Create a file *FormatterTestData.simple*.
|
|
|
|
```bash
|
|
# 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
|
|
```
|
|
|
|
### 2. Define a test method
|
|
|
|
```java
|
|
public void testFormatter() {
|
|
myFixture.configureByFiles("FormatterTestData.simple");
|
|
CodeStyleSettingsManager.getSettings(getProject()).SPACE_AROUND_ASSIGNMENT_OPERATORS = true;
|
|
ApplicationManager.getApplication().runWriteAction(new Runnable() {
|
|
@Override
|
|
public void run() {
|
|
CodeStyleManager.getInstance(getProject()).reformat(myFixture.getFile());
|
|
}
|
|
});
|
|
myFixture.checkResultByFile("DefaultTestData.simple");
|
|
}
|
|
```
|
|
|
|
### 3. Run the test
|
|
|
|
Run the test and make sure it's green.
