tutorial

Writing Tests with Spock

Learn about the Spock testing framework by creating a project that uses Spock to unit test Java code

Part of tutorial

A Simple Assertion

Writing our first Spock test

Part of tutorial

Creating a Project for Spock

Start by creating a new Java project which will be the basis for the rest of this tutorial.

Part of tutorial

Data Tables

Data tables offer the same functionality as data pipes, but this syntax can sometimes be more readable for more complex sets of data.

Part of tutorial

Given, When and Then

See how Spock tests are usually structured.

Part of tutorial

Expecting Exceptions

Tests don't check just the happy paths, sometimes we want to say we're expecting a specific Exception.

Part of tutorial

Data Pipes

Often we want to test the same set of criteria with different sets of data. Data pipes is one mechanism to do this.

Part of tutorial

Helper Methods

Sometimes we need to move test code into a separate method. In this section, we look at some tips for this.

Part of tutorial

Groovy Tips for Java Developers

Groovy's syntax and functionality might be unusual for Java developers to begin with, but it can be very helpful for testing.

Part of tutorial

Introduction

Introduction to the tutorial and links to further reading.

Part of tutorial

Label Flexibility

Spock supports a range of different test labels to help you write the most readable tests

Part of tutorial

Setting up the Dependencies

Add Spock framework dependencies to the project

Part of tutorial

Shortcuts used

Finally, let's summarise the shortcuts we've learnt and see links to further information.

Part of tutorial

Setup and Teardown

See how to set up, or clean up, test classes and methods in Spock.

Part of tutorial

Mocks

Mocks are a useful testing tool. We can provide "empty" objects, so we don't have to initialise the whole application to test a section, and we can use mocks to check our code is making the calls we expect.

Part of tutorial

Specifications as Documentation

Spock tests don't just tell the computer how to test the application, they can help developers understand what the application is supposed to do.

Part of tutorial

Verify All

Test frameworks often stop the test at the first failure. Find out how to run all conditions to see which pass and which fail.

Part of tutorial

Spock IntelliJ IDEA Plugin

Add the Spock plugin to IntelliJ IDEA to get some extra help in the IDE.

Part of tutorial

Stubs

Stub objects allow us to state from a test what values get injected into our application code. They can provide simple interfaces, so we don't have to initialise the whole application to test a section.

Part of tutorial

With

Sometimes we want to check more than one value on an object. We can use `with` to do this.

Part of tutorial

Running Gradle tasks

There are several convenient ways to run Gradle tasks from IntelliJ IDEA.

Part of tutorial

Tour of a Gradle project

Take a look around a standard Gradle project to understand it better.

tip

Change your code font weight

We spend hours looking at our code. We can make this as pleasant as possible.

tip

Prevent a package depending upon another

Enforce architecture rules, such as data access layers not depending upon UI layers.

tip

Profile your application

See how your application is performing with the built-in profiler

tip

Run your code with Docker, SSH or WSL

Set a Run Target to change where your code runs

tip

Tips for working with JetBrains Space

Space is an all-in-one collaboration tool, including chat, code repository, code review, issue tracking, and much more.

tip

Code Reviews with Space

Perform code reviews without leaving the IDE.

tip

Generate UML diagrams for your Kotlin code

JVM developers working with Kotlin code can create UML diagrams for their Kotlin classes, just like they could with Java classes

tip

Use a lightweight inspection profile on commit

Fully customise the checks you must perform before you commit your changes to version control

tip

Sealed types are a new idea for Java developers, let IntelliJ IDEA guide you in how to use them

tip

Create a correct child Sealed Class

Sealed types are a new idea for Java developers, let IntelliJ IDEA guide you in how to create child classes

tip

Evaluate JSON Path expressions

Use IntelliJ IDEA to check if your JSON Path expression are correct.

tip

Turn on Preview Features to try new Java features

The latest versions of Java contain "Preview Features", features that are fully functional but require developer feedback. Try them out in IntelliJ IDEA.
