    Module @tapjs/before - v4.0.2

    Plugin class providing @tapjs/before!Before#before on the @tapjs/test!index.Test class.

    @tapjs/before

    A default tap plugin providing t.before().

    This plugin is installed with tap by default. If you had previously removed it, you can tap plugin add @tapjs/before to bring it back.

    import t from 'tap'
    t.before(() => {
    // this will run before the tests in this file start
    })

    If the method returns a promise, it will be awaited before moving on to the next test.

    A t.before() method will run prior to any subsequent child tests. If it's called before any child tests have started, then it will be run right away.

    So, this test:

    import t from 'tap'

    t.before(() => {
    console.error('before initial')
    })

    t.test('first test', t => {
    t.before(async () => {
    // this will wait before moving on
    await new Promise(res => setTimeout(res, 100))
    console.error('before in first test')
    })
    console.error('in first test')
    t.test('child test', t => {
    console.error('child of first test')
    t.end()
    })
    t.end()
    })

    t.before(() => {
    console.error('before between')
    })

    t.test('second test', t => {
    console.error('in second test')
    t.end()
    })

    will print:

    before initial
    in first test
    before in first test
    child of first test
    before between
    in second test

    Essentially, t.before() is a bit like a child test method that doesn't get a Test object as an argument.
