Lifecycle
Test LifeCycle
Diff between class func vs func
class gets called only once when the class is initialized.
func gets called every time a test case is initialized.
override class func setUp() { }
override func setUp() { }
Sample Code
import XCTest
@testable import TestCaseLifecycle
class TestCaseLifecycleTests: XCTestCase {
// This code is based on Apples' documentation https://developer.apple.com/documentation/xctest/xctestcase/understanding_setup_and_teardown_for_test_methods
override class func setUp() { // 1.
super.setUp()
// This is the setUp() class method.
// It is called before the first test method begins.
// Set up any overall initial state here.
print("LOG: Class setup")
}
override func setUp() { // 2.
super.setUp()
// This is the setUp() instance method.
// It is called before each test method begins.
// Set up any per-test state here.
print("LOG: instance method setup")
}
func testMethod1() { // 3.
// This is the first test method.
// Your testing code goes here.
print("LOG: test method 1")
addTeardownBlock { // 4.
// Called when testMethod1() ends.
print("LOG: teardown block test method 1")
}
}
func testMethod2() { // 5.
// This is the second test method.
// Your testing code goes here.
print("LOG: test method 2")
addTeardownBlock { // 6.
// Called when testMethod2() ends.
print("LOG: first teardown block test method 2")
}
addTeardownBlock { // 7.
// Called when testMethod2() ends.
print("LOG: second teardown block test method 2")
}
}
override func tearDown() { // 8.
// This is the tearDown() instance method.
// It is called after each test method completes.
// Perform any per-test cleanup here.
super.tearDown()
print("LOG: instance method tearDown")
}
override class func tearDown() { // 9.
// This is the tearDown() class method.
// It is called after all test methods complete.
// Perform any overall cleanup here.
super.tearDown()
print("LOG: Class tearDown")
}
