Quickly test expectations
t is a simple testing framework using closures and errors. You have the ability to create a suite that has multiple steps, expectations, and asserts. Expectations can be used to expect one or multiple assertions.
t can be used to test quickly inside a function to make sure something is working as expected. t can also be used in unit tests if wanted.
t.suite {
// Add an expectation that asserting true is true and that 2 is equal to 2
try t.expect {
try t.assert(true)
try t.assert(2, isEqualTo: 2)
}
// Add an assertion that asserting false is not true
try t.assert(notTrue: false)
// Add an assertion that "Hello" is not equal to "World"
try t.assert("Hello", isNotEqualTo: "World")
// Log a message
t.log("📣 Test Log Message")
// Log a t.error
t.log(error: t.error(description: "Mock Error"))
// Log any error
struct SomeError: Error { }
t.log(error: SomeError())
// Add an assertion to check if a value is nil
let someValue: String? = nil
try t.assert(isNil: someValue)
// Add an assertion to check if a value is not nil
let someOtherValue: String? = "💠"
try t.assert(isNotNil: someOtherValue)
}try t.expect {
let someValue: String? = "Hello"
try t.assert(isNil: someValue)
}try t.assert("Hello", isEqualTo: "World")t.log("📣 Test Log Message")XCTAssert(
