快速测试预期
t
是一个使用闭包和错误的简单测试框架。您可以创建一个包含多个步骤、预期和断言的 suite
(测试套件)。预期可以用来 expect
(期望)一个或多个断言。
t
可以用于在函数内部快速测试,以确保某些东西按预期工作。如果需要,t
也可以用于单元测试。
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")
