@tapjs/before

A default tap plugin providing t.before().

USAGE

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.

``ts
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:

`js
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.
