Testing is an essential part of the software development life cycle. A good automated testing suite streamlines feedback, allowing rapid creation and tight control over specific application components.

This course is a comprehensive introduction to testing Elixir applications with ExUnit. You’ll start with a review of unit testing principles before diving into writing tests with the ExUnit. You’ll build a comprehensive suite of unit tests before moving on to more advanced testing, including integration, end-to-end, and property-baste testing. In addition to the core Elixir environment, you’ll also develop tests for OTP, the Phoenix web framework, including JSON APIs and Ecto schematics. You’ll also explore refactoring for different platforms, server rendering, and design strategies.

By the end of this course, you’ll be an expert in unit testing Elixir applications with ExUnit and ready to build robust, performant applications using Phoenix.

Ensuring Elixir Application Performance with Testing and ExUnit

What is a library used to define test doubles instead of faking the whole interface?

What is a library used to define test doubles instead of faking the whole interface?

1) Create the `mocks.ex` file.
2) Put all `Mox.defmock/2` calls in `mocks.ex`.
3) Tweak `mix.exs`.

1) Put all calls in `mocks.ex`.
2) Duplicate the calls in `Mox.defmock/2`.
3) Tweak `mix.exs`.


1) Put all calls in a new file `mocks.ex`.
2) Update `Mox.defmock/2` so that Elixir will automatically compile the `mocks.ex` file.
3) Tweak `mix.exs`.

In order to define mock modules at compile-time, the following changes should be made in which order:


In order to define mock modules at compile-time, the following changes should be made in which order:

The API we are using has a usage limit in a specified time.

Our test depends on the availability of a third-party system.

The APIs sometimes provide staging instead of real service which can generate faulty data.

What is a disadvantage of sending real requests to an external API?

What is a disadvantage of sending real requests to an external API?

1) Add the `:plug_cowboy` dependency to mix.exs in `:test` environment.

2) Define a plug that exposes the endpoint by using `Plug.Router`

3) Initiate the server on a port

1) Initiate the Ad-hoc server on port `4040`

2) Start talking to the server right away

1) Call the **CowBoy** library to initiate the **Plug** server.

2) Add dependency using the Mox library.

3) Start the ad-hoc server on a port.

An ad-hoc server requires what following changes be made to the test environment?

An ad-hoc server requires what following changes be made to the test environment?

What is the dependency used to avoid hard-coding strings in test server code is referred to as?

What is the dependency used to avoid hard-coding strings in test server code is referred to as?

The requests of a third-party API can be recorded and replayed with what?

The requests of a third-party API can be recorded and replayed with what?
