Different between Manual testing and Automation testing | Which one is the best?

Hey all,

In this blog, I will give you a brief knowledge about Manual testing and Automation testing.

What is manual testing?

Manual Testing is the best test plan for every software development company because by following these testing steps you can create some test cases. You will inform the Developer and the manager of your test case report. The test cases will identify your developer and manager as to whether this project is completed or not.

In the manual testing process, you have completed the testing process with human hands because you have completed the testing without using the automation testing tools. After completing the testing you have to prepare test results and these test results will be decided whether all the functions are working or not. You can follow the SDLC process for Good results in the testing.

There are multiple types of testing processes in manual testing

  1. Requirements Analysis
  2. Test plan Creation
  3. Test case Creation
  4. Test case Execution
  5. Defect logging
  6. Validation & Verification.

How does the manual testing work?

Manual testing is effective because it involves humans who do not utilize automation testing tools to complete the tasks. And due to this reason we are calling this type of testing is manual testing.

The result of manual testing is very effective because in this testing process, a tester will create all types of test cases if the functions are not working.

Work of manual testing –

Suppose you have an application, and you want to provide it to users. However, there is a concern regarding whether the application will function correctly or not. Due to this uncertainty, every company needs a tester. This tester will assess your application to determine whether its functions are working properly. The testing process can involve both manual and automation testing, depending on the choice made by the company.

What is Automation testing?

The automation testing tool is expensive, but it does not consume too much time during work. In automation testing, a tester conducts testing with the assistance of automation tools, enabling them to complete the testing efficiently with good results. By using automation tools, a tester can create test cases for all functions and provide information on whether the application or product is functioning properly.

How does Automation Testing Work?

The working efficiency of automation testing is excellent because it takes a short time for testing, providing results easily within a brief duration.

If you are considering working with automation testing, you need to:

  1. Choose a testing tool – Select a tool based on the development requirements.
  2. Define the scope of automation – This means how much of the software testing is automated.
  3. Plan – This is very important to start the testing
  4. Test cases – During the testing if any bug is happening it will be recorded as a test case format
  5. Test case maintenance – We need to update the test cases from time to time.

Tests that are normally automated include the following:

  • Acceptance tests.
  • API tests.
  • Integration tests.
  • Regression tests.
  • Smoke tests.
  • System tests.
  • Unit tests.
  • User interface (UI) tests.

What are the types of Automation testing?

There are certain types of automation tools and companies are using this tool to automate the application and products. Some of them are as follows:

  1. Unit testing – This is the 1st step to start the testing process because of this you can find the error of codes and bugs.
  2. Integration testing – because of this testing process we can know about the module and infrastructure of any products and software.
  3. System testing – This testing is primarily done by manual testers because they test all the features, functionality, security, and performance developed by the developers.
  4. Regression testing – is a continuous process to ensure that newly added functionality works correctly without affecting other parts of the application. It helps guarantee that a newly added feature will not introduce any significant bugs that could break the application.

  • Performance testing – involves assessing the speed, load time, stability, and scalability of an application. It ensures that an application performs according to the specified requirements.
  • Security testing – focuses on the accessibility of an application and its user data. Various tests, such as penetration testing and security scanning, are performed as part of security testing.

Why Use Automation Testing Over Manual Testing?

Because in the manual testing process, a tester will raise the bug manually without the help of automation testing tools. Using the manual testing process takes more time to produce results, and more test cases are created during manual testing.

Let’s say we want to test a significant functionality of an app across 50-60 multiple web browsers, devices, and operating systems; manual testing is not the ideal approach. Instead, by using automation tools, you gain access to hundreds of browser-device-OS combinations, saving time and effort.

These are some key reasons to choose automation testing over manual testing:

Automation testing provides numerous advantages compared to manual testing, rendering it an invaluable tool for software development teams. The following highlights key reasons to opt for automation testing over manual testing:

  2. Improved Test Coverage:
    • Automated testing excels in covering a broad spectrum of test cases and scenarios, particularly in complex applications. This ensures the software functions correctly under various conditions, mitigating the risk of undetected bugs reaching production.
  3. Consistency and Accuracy:
    • Automated test scripts execute consistently and accurately, eliminating the human errors inherent in manual testing. This consistency ensures reliable test performance and reduces the chances of bugs being overlooked due to human fatigue or inattention.
  4. Cost-Effectiveness:
    • While the initial setup of automation testing incurs some investment, the long-term cost savings are substantial. Reusable automated tests diminish the need for manual testing efforts and associated labor costs.
  5. Scalability:
    • Automation testing easily scales to accommodate the testing needs of growing applications or complex test suites. Automated test scripts can be effortlessly updated and expanded to support new features, ensuring testing remains efficient as the application evolves.
  6. Integration with Continuous Integration (CI) and Continuous Delivery (CD) Pipelines:
    • Automation testing seamlessly integrates into CI/CD pipelines, triggering automated testing as part of the development and release process. This integration guarantees prompt and thorough testing of new code before deployment to production.
  7. Reduced Risk of Regressions:
    • Automation testing helps prevent regressions and bugs that are reintroduced after code changes. Automated regression tests ensure changes do not break existing functionality, minimizing the risk of unexpected issues in production.
  8. Improved Reporting and Analysis:
    • Automation testing tools provide detailed reports on test results, facilitating bug identification, trend analysis, and insights into software quality. This data-driven approach aids teams in prioritizing bug-fixing efforts and making informed decisions in software development.

Can Automation Testing Replace Manual Testing?

No, automation testing can’t replace manual testing because we need both types of testing to perform the work properly. Manual testing is helpful for complex test cases, whereas automated testing is preferred for simple and repetitive tests. Both testing processes are very helpful in checking the functions of any product or application.
