• Select an area of your interest (any flow at an e-commerce website).

• For an explanation of the home task, order placement in a shop card scenario will be used.

• User Given-When-Then format

• Try to use only one When step

• Use commonly understandable language for it.

Today we will learn:

• Brief history of Cucumber BDD in Java

• The main features of Cucumber Java

• Advantages and disadvantages of the tool

• The similarities with Serenity

• The difference with JBehave.

Today we will learn:

• JDK Versions – which one to use?

• Oracle JDK VS Open JDK

• How to check the current Java version.

• How to download JDK binary

• Configuring Java environment variables

Today we will learn:

• Gradle main features

• Gradle Versions – Which one to use?

• Prerequisite for Gradle installation

• How to check the current Gradle version

• How to download Gradle binary

• Configuring Gradle environment variable

Today we will learn:

• What is IDE?

• What are the most popular IDEs for Java development?

• Why IntelliJ IDEA?

• How to install IntelliJ IDEA to your machine?

• How to perform the basic configuration of IntelliJ IDEA?

Today we will do the following:

1. Add io.cucumber:cucumber-java:latest test implementation dependency.

2. Add io.cucumber:cucumber-junit-platform-engine:latest test implementation dependency.

3. Add features folder

4. Add steps folder

5. Make sure all the dependencies are loaded.

6. Install Cucumber plugin for IntelliJ

Today we will do the following:

1. Create TwoNumbersAdditionSteps class in steps folder

2. Create twoNumbersAddition.feature in features folder

3. Create a scenario with two Given, one When, and one Then steps

4. Create step mappings in TwoNumbersAdditionSteps class.

5. Store numberOne, numberTwo, and result in separate fields of the class.

6. Assert two numbers sum with JUnit assertion.

Today we will do the following:

1. Add getBoards.feature to features folder

2. Add GetBoardsSteps in steps folder

3. Copy-paste requestWithoutAuth() and requestWithAuth() methods from BaseTest class.

4. Set RestAssured base URL in requestWithoutAuth() method

5. Convert each line of checkGetBoardTest into BDD step def.

6. Create request and Response private fields in GetBoardsSteps class.

7. Make all assertions via .then() statement.

Today, we will discuss the following:

• Migration of JUnit 5 test to Cucumber BDD Scenario.

• Scenario steps definition in feature file.

• Scenario steps mapping in Steps class.

• Merge of similar steps into single.

Today we will:

• Discuss cucumber step parameters.

• Inject dynamic query params for REST Request.

• Merge path params setup steps into a single step.

• Use a single step for checking any status code.

• Verify response against any JSON Schema.

• Verify any body param for any expected value

The home task for today's lesson is:

• Transform UpdateBoardTest class into feature file.

• Parameterize the request is sent to endpoint step.

• Add step that injects header to REST request.

• Add step that passes body params to REST request.

• Use hard-coded value for updated board name temporarily.

Today we will do the following:

• Discuss what Data Table in Cucumber is.

• See where Data Table is used.

• Add data table for query and path params injection.

• User data table with and without headers.

The home task for today is:

• Transform as many parameters as we can to data tables.

• Use data table for response body validation.

• Apply data table for headers param injection.

• Initialize request body as data table map.

Today we will do the following:

• Migrate board validation tests to Outlines

• Split feature files by packages.

• Remove already migrated JUnit test classes.

• Add 'request without auth' Given step.

• Add step to check response body as string.

The hometask for today's lesson is massive:

• Migrate update, create and delete board scenarios to outlines.

• Delete migrated Test classes.

• Delete unused validation arguments holders and providers.

• Delete unused Boards Endpoints URLs.

• Add mappings for POST and DELETE requests to be sent.

Today we will discuss the following:

• What are Backgrounds.

• How are the Backgrounds used.

• Apply Background for Get Boards feature.

• Why no hometask is needed today :)

Today we will:

• Create ScenarioContext class.

• Put all data to share to ScenarioContext.

• Learn what ThreadLocal is.

• Wrap all data to share with ThreadLocal.

• Split your steps into action and assertion.

The hometask for today's lesson is:

• User more elegant way to share test data.

• Add picocontainer dependency to your project.

• Get rid of static keywords in your scenario context.

• Inject ScenarioContext as your step classes' fields.

• Run all the tests to check your updates.

Today we will:

• Learn what Step Arguments Transformers are.

• Merge two steps to create request.

• Create an enum to store endpoints.

• Use arguments transformer to work with the enum

The hometask for today's lesson:

• Remove key and token from scenario.

• Create a Map Transformer class.

• Use @DataTableType annotation.

• Store key and token values in Constants class.

Today we will learn:

• What are hooks and tags in Cucumber.

• Add Delete Board feature.

• Add a step to assert board absence.

• Add a hook to create board before scenario.

• Add Request Auth provider class.

The hometask for today's lesson is:

• Add Create Board feature.

• Run a deleteBoard hook after scenario.

• Add a step to assert board presence.

• Remove migrated tests.

• Remove not needed contants.
