# UnitTests

UnitTests demonstrates how to implement unit tests and UI tests. It is a workspace that contains two projects: Calc and Calc (macOS).

Calc builds an iOS app and CalculatorKit. Calc (macOS) builds an macOS app and a macOS version of CalculatorKit. Both apps use 

CalculatorKit, which is a framework, to process user input and perform related arithmetic operations.

## Build Requirements

+ Xcode 9.3 or later

+ iOS 11.3 SDK or later

+ macOS 10.13 SDK or later

## Runtime Requirements

+ iOS 9.3 or later

+ mac OS 10.11 or later

### iOS

The Calc project defines two schemes:

Calc

Builds the Calc app and performs its UI tests.

CalculatorKit

Builds the CalculatorKit framework. Performs unit tests on the Calculator class.

### macOS

Calc (macOS)

Builds the macOS Calc app and performs its UI tests.

CalculatorKit (macOS)

Builds the macOS version of CalculatorKit. Performs unit tests on the Calculator class.

### Running Unit Tests

To run unit tests,

1. From the Scheme pop-up menu in the toolbar, select CalculatorKit (iOS) > <device_simulator> or CalculatorKit (macOS) > <Mac>

2. Use either of the following approaches to proceed:

a. Choose Product > Test to run all the test cases implemented in the Calculator.m file, then navigate to View > Navigators > Show Report Navigator to view the test results.

See [Xcode Help > Run and Debug > View and filter logs and reports](http://help.apple.com/xcode/mac/current/#/dev21d56ecd4) for more information.

b. Choose View > Navigators > Show Test Navigator to navigate to the Test navigator. Hover the pointer over any test target or test class to display a run button, then click

the button to run the tests. See [Xcode Help > Run UI tests and unit tests](http://help.apple.com/xcode/mac/current/#/dev42b289fbc) for more information.

## Running UI Tests

To run UI tests,

1. From the Scheme pop-up menu in the toolbar, select Calc (iOS) > <device> or Calc (macOS) > <Mac>.

2. Use either of the following approaches to proceed:

a. Choose Product > Test to run all the test cases implemented in the Calculator.m file, then navigate to View > Navigators > Show Report Navigator to view the test results.

   See [Xcode Help > Run and Debug > View and filter logs and reports](http://help.apple.com/xcode/mac/current/#/dev21d56ecd4) for more information.

b. Choose View > Navigators > Show Test Navigator to navigate to the Test navigator. Hover the pointer over any test target or test class to display a run button, then click

   the button to run the tests. See [Xcode Help > Run UI tests and unit tests](http://help.apple.com/xcode/mac/current/#/dev42b289fbc) for more information.
