  /**
   * Generic test function that can be used to cover the scenarios where a generator is creating both a source file
   * and a test file. The function will run the respective generator, and then check for the existence of the two
   * generated files. A RegExp check is done on each file, checking for the generated content with a pattern.
   *
   * The number of parameters is quite huge due to the many options in which the generated files differ,
   * e.g. Services start with an upper case letter, whereas filters, directives or constants start with a lower case
   * letter.
   *
   * The generated items all use the dummy name 'foo'.
   *
   * @param generatorType The type of generator to run, e.g. 'filter'.
   * @param specType The type of the generated spec file, e.g. 'service' - all service types (constant, value, ...)
   *    use the same Service spec template.
   * @param targetDirectory The directory into which the files are generated, e.g. 'directives' - this will be
   *    located under 'app/scripts' for the sources and 'test/spec' for the tests.
   * @param scriptNameFn The function used to create the name of the created item, e.g. _.classify to generate 'Foo',
   *    or _.camelize to generate 'foo'.
   * @param specNameFn Same as scriptNameFn, but for the describe text used in the Spec file. Some generators use
   *    _.classify, others use _.camelize.
   * @param suffix An optional suffix to be appended to the generated item name, e.g. 'Ctrl' for controllers, which
   *    will generate 'FooCtrl'.
   * @param done The done function.
