Test Formatting

To configure the format of tests written by Cover Plugin, go to Diffblue > Change Settings > Test Formatting in IntelliJ.

IntelliJ Code Style Formatting Compatibility

It's important to note that the formatting of tests produced by Cover Plugin for IntelliJ, especially regarding indentation and other style settings, is in line with your current IntelliJ Code Style configurations. This ensures that the generated tests adhere to the code style settings you've set up in your IDE. If you experience formatting conflicts with other tools, such as Spotless, you might need to align your IntelliJ code style settings with those tools to maintain consistency.

You are able to turn off IntelliJ Code Style formatting through the Diffblue settings menu "Apply code style formatting". With this setting turned off tests will be formatted in a way that will match the output of Cover CLI.

Test Styles

Select your preferred Test Style from the drop-down menu ( Brief, Standard, Verbose, or Custom). Selecting Brief, Standard, or Verbose will configure preset settings for the individual formatting options. The Custom style allows you to configure the options as you wish.

Brief Test Style

Using this style, Diffblue Cover will create tests in a more condensed format - the contents of the Arrange and Act sections are inlined into the Assert section, for example:

  @Test
  public void testHasItem() {
    assertFalse((new Order()).hasItem());
  }

Standard Test Style

Using this style provides a compromise between the Brief and Verbose styles. The Arrange, Act, and Assert sections will be labelled, but may still be combined together by inlining if they're small, for example:

@Test
public void testHasItem() throws Exception {
  // Arrange and Act
  boolean actual = (new Order()).hasItem();

  // Assert
  assertEquals(false, actual);
}

Verbose Test Style

Using this style, Cover Plugin creates tests containing up to three commented sections - Arrange, Act, and Assert. For example:

@Test
public void testHasItem() throws Exception {
  // Arrange
  Order order = new Order();

  // Act
  boolean actual = order.hasItem();
  boolean resultBoolean = false;

  // Assert
  assertEquals(resultBoolean, actual);
}

Custom Test Style

Selecting the Custom style allows you to configure the formatting options as you wish. Also note that changing any of the default options for Brief, Standard, or Verbose will automatically change the Test Style to Custom.
