Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The afterClass and beforeClass methods are executed only once."

A block of code is set as follows:

  @Test
  public void currencyRoundsOff() throws Exception {
    assertNotNull(CurrencyFormatter.format(100.999));
    assertTrue(CurrencyFormatter.format(100.999).
      contains("$"));
    assertEquals("$101.00", CurrencyFormatter.format(100.999));
  }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public class LocaleTest {
  private Locale defaultLocale;
  @Before
  public void setUp() {
    defaultLocale = Locale.getDefault();
    Locale.setDefault(Locale.GERMANY);
  }
  @After
  public void restore() {
    Locale.setDefault(defaultLocale);
  }
  @Test
  public void currencyRoundsOff() throws Exception {
    assertEquals("$101.00", 
      CurrencyFormatter.format(100.999));
  }
}

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

green(com.packtpub.junit.recap.rule.TestWatcherTest) success!

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Click on Java build path on the left-hand side and open the Libraries tab."

Note

Warnings or important notes appear in a box like this.
