TestNG @Test Priority in Selenium (Easy)

TestNG Overview

• TestNG covers various test design types, including unit testing, integration testing, functional testing, and end-to-end testing.

TestNG Priority

• If the @Test annotation is not defined with a priority, TestNG assigns a default priority of 0.
• When running multiple test cases with TestNG, the test cases with lower priority values are scheduled first.

Tutorial Scenario

• In the tutorial, sequencing is required when multiple test cases need to be executed in a specific order.
• The expected browser title after performing the scenario in the tutorial is "Facebook - Log In or Sign Up".

Code Structure

• Each step of the code should be self-contained and have a clear purpose.

Purpose of TestNG

• The purpose of TestNG is to provide a testing framework for Java applications.

Browser Launch

• The launchFirefox method is responsible for launching the Firefox browser.

Search Method

• The launchGoogle method is used to launch Google and perform a search.
• The search term used in the performSearchAndClick1stLink method is "facebook".

Facebook Page Title Verification

• The FaceBookPageTitleVerification method is used to verify the title of the Facebook page.
• The method fails if the actual title does not match the expected title.

TestNG Execution

• Without priority, TestNG methods are executed in the order they are defined in the code.
• Assigning priority to test cases in TestNG allows for control over the execution order.
• The purpose of assigning priority is to ensure that critical test cases are executed first.

Priority Definition

• The @Test annotation with the priority attribute is used to define priority in TestNG.
• If priority is defined using a different syntax, it will be ignored.

IDE Compilation

• If priority is defined in a different syntax, Eclipse IDE will show a compilation error.

Priority Case Sensitivity

• TestNG is case-sensitive when defining priority.

Method Priority

• The method with the highest priority value is executed first when priorities are assigned.
• If two methods have the same priority value, the execution order is determined by the method name.

Method Execution

• The method with the highest priority value is executed first when priorities are assigned.
• If priorities are not assigned, the methods are executed in the order they are defined in the code.

Code Example Outputs

• The output of the first code example is the execution of the test cases in the order of their priority.
• The output of the second code example is the execution of the test cases in the order they are defined in the code.
• The output of the third code example is the execution of the test cases with the highest priority value first.
