There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "In this test, we are defining that RuntimeException is expected when the ticTacToe.play(5, 2) method is invoked."

A block of code is set as follows:

public class FooTest {
  @Rule
  public ExpectedException exception = ExpectedException.none();
  @Test
  public void whenDoFooThenThrowRuntimeException() {
    Foo foo = new Foo();
    exception.expect(RuntimeException.class);
    foo.doFoo();
  }
}

Any command-line input or output is written as follows:

    $ gradle test

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "IntelliJ IDEA provides a very good Gradle tasks model that can be reached by clicking on View|Tool Windows|Gradle."
