Usage

$3

`rescript
open RescriptMocha.Mocha
module Assert = RescriptMocha.Assert

describe("Array.map", () => {
it("should map the values", () =>
Assert.deepEqual(Array.map([1, 2, 3], i => i * 2), [2, 4, 6])
)

it("should work with an empty array", () =>
Assert.deepEqual(Array.map([], i => i * 2), [])
)
})
`

$3

`rescript
open RescriptMocha.Promise_

describe("Async tests", () => {
it("should resolve after delay", () => {
Promise.make((resolve, _reject) => {
setTimeout(() => resolve(42), 100)->ignore
})->Promise.then(value => {
Assert.equal(value, 42)
Promise.resolve()
})
})
})
`

$3

`rescript
open RescriptMocha.Async

describe("Callback tests", () => {
it("should call done when complete", done => {
setTimeout(() => done(), 100)->ignore
})
})
`

API

- Mocha - Synchronous describe, it, before, after, beforeEach, afterEach
- Promise_ - Promise-based async versions
- Async - Callback-based async versions (done-style)
- Assert - Node.js assert module bindings

Each module also provides _only and _skip variants (e.g., it_only, describe_skip).
