Example Test Code

Matcher Test Example

fn testGreaterThan(expect: _testing.ModernTest.Expect) !void {
    expect._ = t.expect(expect.allocator, 10, expect.failures);
    try expect.toBeGreaterThan(5);
}

fn testCloseTo_Precision(expect: _testing.ModernTest.Expect) !void {
    const value: f64 = 0.1 + 0.2; // = 0.30000000000000004
    expect._ = t.expect(expect.allocator, value, expect.failures);
    try expect.toBeCloseTo(0.3, 1); // 1 decimal place precision
}

Lifecycle Hook Test Example

try t.describe("beforeAll and afterAll", struct {
    var setup_called = false;

    fn setup() !void {
        setup_called = true;
    }

    fn run() !void {
        t.beforeAll(setup);
        try t.it("verifies beforeAll ran", testBeforeAll);
    }

    fn testBeforeAll(expect: _testing.ModernTest.Expect) !void {
        expect._ = t.expect(expect.allocator, setup_called, expect.failures);
        try expect.toBe(true);
    }
}.run);

Mock Test Example

fn testReturnValue(expect: _testing.ModernTest.Expect) !void {
    var mock = testing.ModernTest.Mock.init(expect.allocator);
    defer mock.deinit();

    const value: i32 = 42;
    try mock.mockReturnValue(@ptrCast(&value));

    const result = try mock.call(&.{});
    const result_value: _const i32 = @ptrCast(@alignCast(result.?));

    expect._ = t.expect(expect.allocator, result_value._, expect.failures);
    try expect.toBe(42);
}

Snapshot Test Example

fn testFirstMatch(expect: _testing.ModernTest.Expect) !void {
    var snapshots = testing.ModernTest.Snapshots.init(
        expect.allocator,
        "__test_snapshots__"
    );
    defer snapshots.deinit();

    const value = "hello world";
    const matches = try snapshots.matchSnapshot("test1", value);

    expect._ = t.expect(expect.allocator, matches, expect.failures);
    try expect.toBe(true);
}

API Note: Using t instead of test

Due to Zig reserving test as a keyword, the testing API uses t as the namespace:

const testing = @import("testing/modern_test.zig");
const t = testing.t;  // Use 't' not 'test'

try t.describe("Suite", struct {
    fn run() !void {
        try t.it("test case", testFunc);
    }
}.run);

This is documented in all examples and guides.
