The Future of Manual Testing in the Age of AI

1. Common Manual Testing Techniques:

     Manual testing techniques are essential for ensuring the functionality, usability and reliability of software. Each testing technique serves a different purpose and is suited for different stages of the software development lifecycle. As a tester understanding the techniques and knowing when and how to apply them will enable you to identify defects early, improve the quality of the software, and contribute to a better user experience.

    While automation testing can be an effective way to speed up repetitive tasks, manual testing remains a vital part of the overall testing strategy, especially for scenarios that require human intervention, judgment and creativity.

2. Boundary Value Analysis:

     Boundary Value Analysis is a structured black box testing technique that targets the end points or “boundaries” of input domains. For example, if a system accepts ages from 18 to 60, test values like 17, 18, 19, 59, 60, and 61 should be prioritized because errors typically lurk at or around these limits.

Benefits of Boundary Value Analysis:

Cost Savings
Higher Product Quality
Improved Customer Trust
Faster Release Cycles
Lower Support Load
Compliance Assurance
Scalability

3. Decision Table Testing:

  Decision Table Testing is a black box test design technique in which test cases are designed to execute the combinations of inputs shown in a decision table. Decision table testing is a good way to deal with combinations of inputs.

Example: Making of Decision Base Table for Login Screen
Specification:

Let’s take the example of a login screen of say any transport application. The condition states that if the user provides the correct username and password the user will be redirected to the homepage. If any of the input is wrong, an error message will be displayed on the screen.

Decision Table for Login Screen:

Conditions Rule 1/TC1 Rule 2/TC2 Rule 3/TC3 Rule 4/TC4

Email Id (Input) T T F F
Password (Input) T F T F
Action(Output) H E E E

In the above example, the

T stands for correct Email id/password.

F stands for incorrect Email id/password.

H stands for Home screen to be displayed to the user.

E stands for the Error message to be displayed to the user.

TC stands for the Test case.

4. The Future of Manual Testing in the Age of AI:

  Manual testing remains a crucial component of the QA process, even in the age of AI. Human testers bring a unique perspective and skill set that complements the capabilities of AI-driven tools. They possess domain knowledge, critical thinking abilities, and problem-solving skills that enable them to identify defects and edge cases that automated scripts might overlook.

 Manual testers conduct manual quality assurance in a way that it can provide valuable insights into the user experience, ensuring that the software meets the needs and expectations of end-users. They can also validate the results of AI-driven testing, verifying that the outcomes align with business requirements and user expectations.
