Software Testing

Automation testing tool

Selenium is a powerful tool for web automation and testing, and is widely used by developers and testers around the world. It is an open-source software suite that is widely used for automating web browsers. It provides a framework for testing web applications and supports a variety of programming languages, including Java, Python, C#, and Ruby. Selenium can be used to automate various tasks related to web browsing, such as testing the functionality of a website, scraping data from web pages, and interacting with web-based user interfaces. It works by automating interactions with web browsers such as Chrome, Firefox, and Internet Explorer, allowing developers and testers to simulate user behavior and automate repetitive tasks. It is highly customizable and extensible, with a variety of plugins and add-ons available to enhance its functionality. It can be used in a variety of settings, including agile development environments, continuous integration and delivery pipelines, and exploratory testing scenarios.


Automation Testing

Automation software testing is an essential tool for software development teams, and is widely used to improve the quality, reliability, and efficiency of software applications. There are several benefits to automation software testing, including:

  • Automated tests can be run faster and more frequently than manual tests, allowing developers to identify and fix issues more quickly.

  • Testscripts less prone to errors and inconsistencies than manual tests, which can improve the accuracy of test results.

  • Once created, automated test scripts can be reused across multiple testing cycles, which can save time and effort.

  • Automated tests provide consistent results, which can help developers identify and resolve issues more effectively.


Manual testing 

Manual testing is useful when a high degree of human judgement, intuition, and creativity is required. 
While automated testing can be faster and more efficient, it cannot replace the expertise and judgement of a human tester in many scenarios. Therefore, a combination of manual and automated testing is often used to achieve the best results.

When testing a new feature or functionality, manual testing is often preferred because it allows testers to explore the system and identify unexpected behavior. In situations where a bug or issue is reported by a user, It may be the quickest and most effective way to 
reproduce and diagnose the problem. Also it can be useful for verifying that the user interface is intuitive and easy to use. When testing the usability of a system, often manual testing is adopted because it allows testers to observe how users interact with the system and identify areas for improvement. As well, for testing localized versions of a software application manual testing is the best one, as it allows testers to verify that the language, cultural conventions, and other localization-related features are correctly implemented.


Automation tools

There are many automation tools available for software testing, each with its own strengths and weaknesses. When selecting an automation tool, it is important to consider the application type, programming language, and features required for your specific testing needs..

Some popular automation tools

It provides a variety of features, including record and playback, keyword-driven testing, and test scripting.

API Testing

API testing is the process of verifying/validating functionality, responses, and status code of an application programming interface (API).

API testing involves testing the inputs and outputs of an API, as well as the overall behavior and functionality of the API.

API testing can be automated or performed manually.

How to test an API?

  • The first step in API testing is to understand the API and its intended functionality.

  • This includes understanding the input parameters, expected outputs, and error handling mechanisms.

  • Once we get a clear understanding of the API, we can start to develop test cases to verify that the API is functioning correctly.

  • Test cases should cover all possible scenarios, including valid and invalid inputs, error conditions, and edge cases. In order to test the API, we need to create test data that simulates real-world scenarios.

  • The next step is to run the test cases and verify that the API is functioning correctly. This can be done manually or using automated testing tools. Once the tests have been run, the results should be analyzed to identify any issues or defects in the API.

  • API testing can be performed at various levels, including unit testing, integration testing, and end-to-end testing.  Unit testing involves testing individual functions or methods within the API,  while integration testing involves testing how different parts of the API work together.  

  • End-to-end testing involves testing the entire API in a simulated production environment.

Testing tools

Automated testing tools such as Postman, SoapUI, and Swagger can be used to streamline the API testing process and improve efficiency.

These tools can help automate the testing process and provide detailed reports on the API's performance and functionality.  

Benefits of API testing

  • API testing can help detect defects early in the development process, before they can cause more significant problems downstream.  

  • By automating API testing, developers can receive faster feedback on changes they make to the API, allowing them to  identify and correct issues quickly.

  • By ensuring that APIs meet their requirements and function correctly, API testing can improve the overall quality of the software system.

  • It can help facilitate communication between development and testing teams, by providing a common language and understanding of the API's functionality.

  • Catching issues early in the development process can help reduce the costs associated with fixing them later in the software development lifecycle.

  • It helps to identify  vulnerabilities and security weaknesses in the API,  allowing them to be addressed before they can be exploited by attackers.

  • Automating API testing can help save time and increase productivity, allowing developers to focus on other important tasks.
