Framework of automated tests with JUnit, Java, and Maven

Framework to test in the unit layer.

To practice this I built a class to calculate the Body Mass Index (BMI) and a test class to test the methods of retrieving a result based on a size and a weight of a person.

I used a data-driven approach to run the test class using a csv file with different data and also a structure of Suites so I can run tests in an optimized way. There are 3 Suites of tests basically. One with Positive scenarios and another with Smoke tests with the most important ones. A third Suite runs all test classes as long as I parameterize them. It is also possible to run the tests with CLI and the results we can view with Allure Report.

Pre-conditions

• src: main dir
• main: dir with the base code
• java: default dir when the project is created
• bmi: package with base code classes
• BMI: class with the Body Mass Index logic
• categories: package with interfaces to support the Suite approach
• test: package with test classes
• java: default dir when the project is created
• bmi: package with test classes
• CalculateBMI_CSVTest: test class with the data-driven approach that consumes the csv file
• CategorizedTestsTest: test class with categorized methods that will support Suite classes based on categories
• Suite_AllTestsTest: test class to parameterize all classes you want to run easily with one click
• Suite_PositiveCatergoriesTest: test class to parameterize all methods categorized as Positives
• Suite_SmokeCatergoriesTest: test class to parameterize all methods categorized as Smoke
• resources: dir with csv file

CLI

Run all test classes through command line:

mvn surfire:test

As soon as the tests are executed, a folder will be created inside the "target" directory, called "surefire-reports".

Report

Open the Allure test report via command line:

allure serve /PATH*

*The path must be changed to the path of the "surefire-reports" folder created in the previous step.
