the class RefasterJsTestUtils method assertFileRefactoring.

/**
 * Performs refactoring using a RefasterJs template and asserts that result is as expected.

 *     apply
 * @param testDataPathPrefix path prefix of the directory from which input and expected-output
 *     file will be read
 * @param originalFile file name of the JavaScript source file to apply the refaster template to
 * @param additionalSourceFiles list of additional source files to provide to the compiler (e.g.
 *     dependencies)
 * @param expectedFileChoices the expected result options of applying the specified template to
 *     {@code originalFile}
