Troubleshooting

An invalid amount of arguments were specified for a Suite

Suite initialisers accept only one, two, or three arguments, as shown by the following snippets:
one-arguments.js
two-arguments.js
three-arguments.js
// 1 arguments
suite('name', function (suite) {
suite('an immediate suite', function (suite, test) {
test('an immediate test', function () {})
})
})
// 2 arguments
suite('name', function (suite, test) {
test('an immediate test', function () {})
})
// 3 arguments
suite('name', function (suite, test, done) {
setTimeout(function () {
test('a delayed test', function () {})
done()
}, 1000)
})
This is to ensure a suite is not confused with a test.
Resolving this error involves checking your logic to ensure that you actually want to use a Suite:
  • if you do want to use a suite, then update the specified arguments to a combination mentioned above
  • if you don't want to use a suite, then you may want to use a test instead

An invalid amount of arguments were specified for a Test

Tests only accept zero or one arguments, as shown by the following snippets:
zero-arguments.js
one-arguments.js
// 0 arguments
test('an immediate test', function () {
// completes right away
})
// 1 arguments
test('an asynchronous test', function (done) {
setTimeout(function () {
done()
}, 1000)
})
This is to ensure a test is not confused with a suite.
