Why Use Protractor?

Protractor is an open-source automation framework specifically built to verify the functionality and health of AngularJS web applications. It leverages Selenium WebDriver to interact with web browsers, simulating user actions to test application behavior effectively.

Test Syntax and Framework

Protractor primarily uses Jasmine, a behavior-driven development (BDD) framework, for writing test cases. This allows for a clear, structured, and readable test syntax.

Essential Files for Running Protractor

Spec File (Test File)

A spec file contains the actual test cases. Multiple spec files can be grouped into a Test Suite.

Example Spec File:

describe("A test suite", function() {
 it("Should show something", function() {
 expect(someText).toEqual(someText);
 });
});
 

Key Components of a Spec File:

• describe(): Defines a test suite with a title and a function that implements the tests.
• it(): Represents an individual test case, taking a title and a function that executes the test.
• expect(): Used for assertions, verifying expected vs. actual outcomes.

Configuration File

The configuration file tells Protractor:

• Where to find the test files (specs).
• The location of the Selenium Server.
• Browser settings and parameters for execution.

Example Configuration File:

exports.config = {
 seleniumAddress: 'http://localhost:4444/wd/hub',
 specs: ['spec.js']
};
 

Key Components of a Configuration File:

• seleniumAddress: Specifies the address of the running Selenium server.
• specs: Defines the location of the spec files.
