Usage
Using LoadNinja is straightforward, making it accessible for teams to conduct load tests effectively. Below is a simple example of how to use LoadNinja to create and execute a load test.
Example: Testing a Web Application Login Page
Suppose you want to test the login functionality of a web application. Here’s how you would do it using LoadNinja:
- Sign Up and Create a New Test:
- Visit the LoadNinja website and sign up for an account.
- Once logged in, create a new load test by clicking on "Create Test."
- Record User Interactions:
- Use the LoadNinja browser to navigate to the web application you want to test.
- Click on the "Record" button in LoadNinja, then perform the login action (entering username and password and clicking the login button).
- LoadNinja captures the interactions and generates a test script automatically.
- Configure Load Test Settings:
- Specify the number of virtual users you want to simulate (e.g., 100 users).
- Set the ramp-up time, which defines how quickly the virtual users will start interacting with the application.
- Define the duration of the test and any specific conditions or scenarios you want to include.
- Run the Load Test:
- Once everything is configured, click on the "Run Test" button to execute the load test.
- LoadNinja will simulate the specified number of users logging into the application simultaneously.
- Review Results:
- After the test completes, navigate to the reporting section to view the results.
- Analyze key metrics such as average response time, error rates, and throughput to assess the application’s performance under load.
Sample Code for Load Test Creation (Pseudocode):
// Pseudocode to represent test scenario creation
let test = new LoadNinjaTest("Login Test");
test.addVirtualUsers(100);
test.setRampUpTime(60); // seconds
test.setTestDuration(300); // seconds
// Define the steps for the login process
test.recordStep("Navigate to login page", "GET", "https://example.com/login");
test.recordStep("Enter username", "POST", {username: "user123"});
test.recordStep("Enter password", "POST", {password: "pass123"});
test.recordStep("Click login", "POST", "https://example.com/login");
test.run();
