Assertion System

DropBear's assertion system can work either as an extension on current XCUI Test capabilities, or it can be paired with DropBear's Robot pattern, shown above.

When used along with DropBear's Robot pattern, assertions also become chainable, giving you clean and concise readability without losing your place as you write your tests.

To better highlight the features of the assertion system, we've broken it out in to two parts.

Assertions

Empty

The .empty assertion is used to check if a String-based value is empty. This will also return true if a UITextField's placeholder value matches the current value of the UITextField.

Example usage:

FooRobot()
    .assert(.fooTextField, .empty)

Enabled

The .enabled assertion is a simple wrapped around element.isEnabled, and can be used with any element type.

Example usage:

FooRobot()
    .assert(.fooButton, .enabled)

Equal

The .equal assertion compares the element's value to another value that the assertion accepts as a parameter. Currently, the accepted types that can be used to validate with are Bool, Double, Int, and String.

Note: The assertion compares values as lowercase, making this assertion case-insensitive.

Example usage:

FooRobot()
    .assert(.fooTextField, .equal(to: "Hello, world!"))

Exists

The .exists assertion checks for the existence of the speicified element. By default, using this assertion will wait for the existence of the element for 5 seconds, after which time it will fail if the element does not exist.

If you would like to override the amount of time that the test waits for the element to exist, DropBear also provides a mechanism for accomplishing that.

Example usage:

FooRobot()
    .assert(.fooTextField, .exists) // Will wait for up to 5 seconds for existence

or

FooRobot()
    .assert(.fooTextField, .exists(waiting: 10)) // Will wait for up to 10 seconds for existence

Contains

The .contains assertion checks the label and value properties of the element for any matches against the parameter passed into the assertion. The only acceptable parameter type is String.

Assuming our example UITextField has a value of Hello, world!, the following example usage would assert true.

Example usage:

FooRobot()
    .assert(.fooTextField, .contains("world"))

Operators

DropBear's assertion system also provides operators for simplifying your test writing.

!

The ! operator is a method that takes an assertion as the only unnamed parameter. This operator inverts the result of the assertion it takes, giving you a not-style result.

FooRobot()
    .assert(.fooTextField, !(.exists))

&&

The && operator evaluates two or more assertion results and only asserts true if all results are true.

FooRobot()
    .assert(.fooTextField, .exists && .contains("world"))

||

The || operator evaluates two or more assertion results and asserts true if any results are true.

FooRobot()
    .assert(.fooTextField, .exists || .contains("world"))
