The Great Debate: Manual Testing vs Automation Testing

What is manual testing?

Manual testing is a critical component of the software development life cycle, and it helps to ensure that the application meets the desired quality standards. Manual testing is the process of manually executing test cases to identify defects in a software application.

It involves human testers who perform testing meticulously by exploring different aspects of the application, such as functionality, user interface, and usability. It requires a curious and detail-oriented approach to ensure that all features are tested thoroughly.

What is a manual testing example?

Imagine you’re a software tester tasked with testing a new chat app. You start by manually typing in various messages to see how the app responds. You try sending emojis, long messages, and even messages with typos to make sure the app can handle anything a user might throw at it.

You also test for different scenarios like poor network connections or full storage on the device. Manual testing allows you to catch bugs and errors that may slip through automated testing, ensuring that the app works flawlessly for its users.

How to write test cases in manual testing?

Manual testing involves the process where testers perform manually for defects, bugs, and other issues that might impact its functionality. One of the crucial aspects of manual testing is writing effective test cases. Test cases are step-by-step instructions that outline the expected behavior of the application under test.

To write effective test cases, you must start by understanding the software requirements and specifications thoroughly. Then, you need to identify the various scenarios that can occur while using the application and create test cases accordingly.

The test cases should be clear, concise, and easy to understand. It should include all the necessary information such as the test objective, input data, expected output, and actual result. Additionally, you should also include the preconditions and post-conditions of the test case.

It is essential to ensure that the test cases cover all the functionalities of the application, and each test case is independent of the other. This helps to ensure that the test results are accurate and can be easily reproduced.

Writing effective test cases in manual testing requires careful planning and attention to detail. By following the above guidelines, you can create well-written test cases that will help you uncover any issues in the application and ensure its functionality.

Manual testing process

The following steps are involved in the software manual testing process:

Step 1: Test Planning – In this step, testers analyze the requirements and create test cases and test scenarios based on the user stories or requirements.

Step 2: Test Execution – In this step, testers execute the test cases and record the test results. They also report the defects to the development team and verify the fixes after they are made.

Step 3: Test Reporting – In this step, testers create a test report summarizing the test results, including the number of test cases passed, failed, and pending.

Step 4: Test Closure – In this final step, testers review the test results with the development team and ensure that all defects have been resolved. They also archive the test artifacts, including test cases, test scenarios, and test reports, for future reference.

When to use test automation vs manual testing?

Ah, the eternal question of automation vs manual testing! While both approaches have their advantages and disadvantages, there’s no one-size-fits-all answer to this conundrum. It all depends on the context and goals of your project.

Manual software testing is a great option when you’re dealing with small-scale projects, or when you need to test something that requires a human touch. Think user experience, user interface, and accessibility testing, for example. Manual testing can also be useful for exploratory testing, where you need to be creative and curious to uncover potential issues.

On the other hand, software testing automation can save you tons of time and effort when you’re dealing with large-scale projects or repetitive tasks. It’s particularly useful for regression testing, where you need to test the same functionality multiple times, or for load testing, where you need to simulate a large number of users.

That being said, there are some caveats to automation testing. For example, it requires a significant upfront investment in terms of time, skills, and resources. Plus, not all testing tasks can be easily automated, especially those that require subjective judgment or human intuition.

So, when it comes down to it, the best approach is to use a mix of both automation and manual testing, depending on your project’s needs. By leveraging the strengths of each approach, you can optimize your testing process and ensure that your product meets the highest quality standards possible.

Types of manual testing

There are several types of manual testing techniques that testers use to ensure the quality of the software.

Let’s explore some of the different types of manual testing:

  • User Acceptance Testing (UAT): UAT involves testing the software from the end-user perspective to ensure that it meets their needs and requirements.

  • Functional Testing: This type of testing verifies if the software is functioning as per the requirements and specifications.

  • Regression Testing: This type of testing is performed to ensure that the changes made in the software do not negatively impact its existing functionalities.

  • Integration Testing: Integration testing involves testing the interaction between different modules or components of the software to ensure that they work together seamlessly.

  • Smoke Testing: Smoke testing is a quick check of the software’s basic functionalities to ensure that it is stable and ready for further testing.

  • Exploratory Testing: Exploratory testing is a technique in which the tester explores the software to identify defects, without any predefined test cases or scenarios.

  • Ad Hoc Testing: Ad hoc testing involves testing the software in an unplanned and unstructured manner to identify defects that may not be found through other testing techniques.

  • Compatibility Testing: This type of testing ensures that the software works seamlessly on different operating systems, browsers, and devices.

  • Security Testing: Security testing involves testing the software to ensure that it is secure against external threats, such as hacking and malware.

  • Performance Testing: Performance testing is conducted to ensure that the software can handle a large number of users and transactions without any performance issues.

Manual testing vs automation testing

Manual testing vs automated testing are two different approaches to software testing. While manual testing involves human intervention to check the functionality of software applications, automation testing involves using tools and scripts to automate the testing process.

Here are 5 key differences between manual qa testing and automation testing:

  • Speed: One of the most obvious differences between manual and automation testing is speed. Manual testing is time-consuming and can take hours or even days to complete, especially for large and complex applications. Automation testing, on the other hand, is much faster as the testing tools and scripts can execute tests much more quickly and efficiently than humans.
  • Human error: Manual testing is prone to human error, as it involves manual interaction with the software application. This can lead to inconsistencies in test results and missed defects. Automation testing, on the other hand, is less prone to human error as it follows pre-defined scripts and algorithms to execute tests.
  • Cost: Manual testing is typically more expensive than automation testing. This is because it requires a larger workforce to perform the tests, which can be costly in terms of salaries, training, and benefits. Automation testing, once set up, can be less expensive as it requires less human intervention and can be executed by a smaller team.
  • Scope: Manual testing is typically limited in scope and can only test a limited number of scenarios. Automation testing, on the other hand, can test a much larger number of scenarios and can cover a wider range of test cases, making it more comprehensive.
  • Maintenance: Finally, maintenance is a key difference between manual and automation testing. Manual testing requires constant monitoring and retesting, especially when new features are added or existing features are updated. Automation testing requires less maintenance, but the testing scripts and tools must be updated regularly to ensure they remain relevant and effective.
