Explore behavior driven development as a style that unites domain driven design and test driven development to deliver stakeholder value through minimal incremental steps and clear software behavior.
This lecture explains how bdd and tdd complement each other by describing behavior, writing step definitions, running tests, failing, and having developers implement code to pass tests.
Learn how Cucumber uses feature files in Gerken language to drive behavior-driven development, binding them to Java step definitions with given, when, then, and scenario concepts.
Explore the cucumber framework for bdd used with selenium for automated tests, and learn the essential prerequisites—jdk, eclipse, selenium webdriver, and cucumber jars—whether you are new or have Java experience.
Verify the Java version in the command prompt, install the JDK (Java 8 or 9), and set up Eclipse or IntelliJ; then download the Selenium jar and other required jars.
Download and assemble selenium and cucumber jar files for eclipse projects from a repository, selecting compatible versions (selenium java, cucumber core, cucumber java, cucumber junit, and JVM deps).
Launch Eclipse, set up a cucumber Java project in your workspaces folder, import external jars, and install the cucumber plug-in from the update site to enable cucumber testing.
Learn to create feature files in Cucumber using BDD and TDD, merging business requirements with technical implementation to drive tests, and organize project folders.
Learn the Gherkin syntax used in Cucumber tests, including features, scenarios, scenario outlines, examples, and background, and recognize keywords like given, when, then, and, but.
Learn to write your first Cucumber feature using the feature keyword, crafting a login feature with a user story that starts with 'as a' to clarify who, what, and why.
Define a scenario as an instance of a feature in Cucumber; features hold multiple scenarios to test different cases; this scenario covers logging in with valid credentials and outlines steps.
Apply the given–when–then structure to a login scenario, specifying preconditions on the logon page, user actions, and outcomes such as viewing the account balance.
Learn to implement glue code by creating step definition classes in Java. Bind feature file steps with Cucumber in a dedicated step definitions package for the login scenario.
Learn how to bind a cucumber step to Java code by creating a function and using given annotations to map it to the feature file step.
Map cucumber steps to Java functions with given, when, and then annotations; implement public void methods like user answers valid credentials and user should see account balance.
Learn how to run a Cucumber feature file for BDD, inspect step definitions and console outputs, and interpret scenario, step, and pass/fail summaries.
This lecture shows managing execution in a cucumber bdd framework with a JUnit test runner, adding a runners package and cucumber options for features and glue.
Add JUnit assertions to a cucumber scenario, compare expected and actual values, run the feature to see failures, and read the failure trace to debug balance mismatches.
learn to integrate the cucumber framework with selenium, set up chrome driver and selenium standalone server, and run basic login tests in eclipse.
Integrate Selenium with Cucumber step definitions by setting up a web driver, navigating to the login page, locating elements by id, and sending credentials to simulate login.
Explore how to implement assertions in a Selenium test using JUnit within a Cucumber framework, by retrieving the page body text and verifying login success or welcome messages.
Leverage Cucumber hooks to perform before and after setup around each scenario by initializing the browser driver and quitting it afterward, improving test reliability.
Define multiple scenarios within a feature by reusing existing step definitions. Start a bad credentials login scenario from login page, use hooks to run shared steps, and run test runner.
Learn to reuse steps and extend feature files with extra Gherkin keywords such as given, when, then, and but, and validate invalid login messages across scenarios.
Learn how to use Cucumber tags to selectively run scenarios or features, combining tags with and, or, and not, and manage tests from the command line.
Learn how the background keyword runs steps before every scenario, enabling shared setup (like user login and navigation) and how to control execution with tags and ignore options.
Create a hooks class to bind before and after hooks to step definitions, exposing a public static web driver shared across classes in a cucumber Java framework.
Learn how to use Gherkin variable placeholders to reveal test data in feature files, and expand steps into explicit, data-driven steps with quoted inputs.
Implement variable placeholders in cucumber with Java by using regular expressions to capture username and password in step definitions, passing data from feature files for data-driven testing.
Learn how to drive tests with multiple data sets using Gherkin's scenario outline and examples, passing variables into steps to run data-driven login scenarios.
Implement data-driven testing in java with cucumber bdd, modeling login steps with username and password across data sets, and refactor with helper functions to run scenarios twice with different data.
Learn how to use gerkin data tables in cucumber bdd to run a single login scenario with multiple data sets, testing bad and good credentials and validating login outcomes.
Implement data-driven login in Cucumber by converting a data table to a map of credentials, iterating to extract username and password, and replaying login steps for each row.
Behavior-driven development, acceptance testing, and test-driven development is one of the latest, most important trends in software delivery. Learn how to implement BDD software delivery with Cucumber framework using Java, Selenium, and JUnit. Apply your knowledge to a real-world application.
