A tool for providing the 2 features for efficient testing:
- Output diff between 2 any types
- Default implementation of Equatable for any types
import MirrorDiffKit
// Input 2 structs or classes implements Equatable:
let a = Example(
key1: "I'm not changed",
key2: "I'm deleted"
)
let b = Example(
key1: "I'm not changed",
key2: "I'm inserted"
)
XCTAssertEqual(a, b, diff(between: a, and: b))
// XCTAssertEqual failed: ("Example(key1: "I\'m not changed", key2: "I\'m deleted")") is not equal to ("Example(key1: "I\'m not changed", key2: "I\'m inserted")") -
// struct Example {
// key1: "I'm not changed"
// - key2: "I'm deleted"
// + key2: "I'm inserted"
// }import MirrorDiffKit
a = NotEquatable(
key1: "I'm not changed",
key2: "I'm deleted"
)
b = NotEquatable(
key1: "I'm not changed",
key2: "I'm inserted"
)
XCTAssert(a =~ b, diff(between: a, and: b))
// XCTAssertTrue failed -
// struct NotEquatable {
// key1: "I'm not changed"
// - key2: "I'm deleted"
// + key2: "I'm inserted"
