API Contract Testing with example using Postman

Contract testing for API is about making sure that the API behaves according to the contract that has been agreed upon, and it can be done using different tools and frameworks.

Here’s an example of contract testing using Postman:

# Import the collection from a file
pm.test("status code is 200", function () {
    pm.response.to.have.status(200);
});
pm.test("response should be a JSON", function () {
    pm.response.to.have.header("Content-Type", "application/json");
});
pm.test("response should be not be empty", function () {
    pm.expect(pm.response.json().data).to.not.be.empty;
});

This code is a test script written in JavaScript, it check if response status is 200, if the response type is JSON and if the JSON response data is not empty. The test will fail if the API does not adhere to the contract, and the developers can use the failure message to identify and fix the issue.

Skills needed to make a transition from Software Test Lead to Testing Manager

To make a successful transition from a Software Test Lead to a Testing Manager, you will need a combination of technical, leadership, and project management skills. Some key skills that are important for a Testing Manager include:

  • Extensive knowledge and experience with software testing processes and methodologies
  • The ability to develop and manage a team of software testers
  • Strong agile project management skills, including the ability to create and manage budgets and schedules
  • Excellent communication and interpersonal skills, including the ability to communicate complex technical concepts to non-technical stakeholders
  • The ability to identify and mitigate project risks
  • The ability to foster collaboration and teamwork among team members
  • Strong problem-solving and critical thinking skills

In addition to these technical skills, it’s also important for a Testing Manager to have strong leadership skills, such as the ability to motivate and mentor team members, provide constructive feedback, and foster a positive and productive work environment.

How to invoke Edge browser in selenium?

To invoke the Microsoft Edge browser in Selenium, you need to use the EdgeDriver class. Here’s an example of how you can do this:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.edge.EdgeDriver;

public class EdgeTest {
  public static void main(String[] args) {
    // Set the path to the Microsoft Edge driver
    System.setProperty("webdriver.edge.driver", "path/to/MicrosoftWebDriver.exe");

    // Create a new instance of the Edge driver
    WebDriver driver = new EdgeDriver();

    // Open a new browser window and navigate to a website
    driver.get("http://www.example.com");
  }
}

Note that you need to download and install the Microsoft WebDriver server in order to use the EdgeDriver class. You can find the download link and instructions on how to install the WebDriver server on the Selenium website.

Benefits of API Test Automation over UI Test Automation? – Mostly asked Interview Question

API testing has many benefits over UI testing:

  • First, API testing is much faster than UI testing. This is because API tests do not have to wait for a page to load, as they interact directly with the application’s backend.
  • Second, API tests are more reliable than UI tests. This is because UI tests are subject to the vagaries of the user interface, such as changes in the layout or position of elements. API tests, on the other hand, are not affected by such changes.
  • Third, API tests are easier to create and maintain than UI tests. This is because UI tests often require a lot of code to simulate user interactions, whereas API tests only need to make calls to the application’s API.
  • Fourth, with API testing, one can find bugs related to functionality, reliability, performance, and security early in the SDLC and hence those are cheaper to fix.

In conclusion, API testing has many advantages over UI testing, and should be used whenever possible.

Thoughts and Ideas on Future of Software Testing.

The future of software testing is likely to be more automated and focused on artificial intelligence (AI) and machine learning. This is due to the increasing complexity of software systems and the need for faster and more accurate testing.

AI and machine learning can help to automate the testing process by generating test cases and test data. They can also help to identify errors and potential areas of improvement. In addition, AI and machine learning can be used to create virtual environments for testing, which can be more realistic and representative of the real world.

As the use of AI and machine learning in testing becomes more widespread, it is likely that the role of human testers will change. They will become more focused on overseeing the automated testing process and interpreting the results.

The future of software testing is likely to be more efficient and effective as a result of the increasing use of AI and machine learning. This will benefit both developers and users by reducing the time and cost of testing, and by improving the quality of software products.
