Manual software testing is not just about running tests. It is a meticulous process divided into several stages: Test Planning and Control, Test Analysis and Design, Test Implementation and Execution, Evaluating Exit Criteria and Reporting, and Test Closure Activities. Let's look at these stages in detail.

Test Planning and Control

In the test planning and control stage, a comprehensive testing plan is crafted. This plan defines the overall testing approach and includes details like the testing scope, objectives, methods, resource allocation, schedule, and risk analysis. Once the plan is prepared, it is reviewed and approved before the test execution begins. The control aspect involves monitoring the progress and adjusting the plan as necessary.

Test Analysis and Design

During the test analysis and design stage, testers start by analyzing the software's requirements and specifications. They then design the test cases and procedures that will be used to verify that the software meets these requirements. This stage also involves preparing test data for the test cases.

Test Implementation and Execution

Once the test cases and data are prepared, the test implementation and execution stage begins. Here, the tester executes the designed test cases manually and compares the actual results with the expected results. Any discrepancies are recorded as defects for further investigation.

Evaluating Exit Criteria and Reporting

After the test cases have been executed, the testers move on to the evaluation stage. Here, they check whether the defined exit criteria have been met, such as a certain number of test cases executed or a certain number of critical bugs fixed. A test report is prepared, detailing the testing activities and their outcomes.

Test Closure Activities

In the final stage, test closure activities are carried out. This includes ensuring that all the testing work has been completed and documented, analyzing the testing process for future improvements, and archiving the test products for future reference.

Key Concepts in Manual Software Testing

To master manual software testing, it's vital to grasp some of its key concepts, namely test cases and bugs or defects. Understanding these components and their handling process is crucial for a successful testing procedure.

Understanding Test Cases

Test cases form the backbone of the manual software testing process. A test case is a set of conditions or variables under which a tester determines whether a system under test satisfies requirements and functions correctly. Each test case includes information on the environment, inputs, expected outcomes, and actual outcomes, serving as a guide to validate a particular functionality of the software application.

Writing Effective Test Cases

Writing effective test cases is an art that requires a deep understanding of the software under test and a keen eye for detail. A good test case should be clear, concise, and comprehensive. It should be clear enough for other testers to understand and execute. It should be concise, yet detailed enough to cover all the scenarios. Lastly, it should be comprehensive, covering all possible inputs, outputs, and error conditions.

Test Case Design Techniques

There are various techniques used to design test cases in manual testing. These include:

• Black Box Testing: This technique is based on the requirement specification and doesn't consider the internal code structure.
• White Box Testing: This technique is based on the internal logic of an application's code.
• Grey Box Testing: A combination of Black Box and White Box testing, this technique tests a piece of software against its specification and the internal workings of the code.
• Boundary Value Analysis (BVA) and Equivalence Class Partitioning (ECP): These are two specification-based techniques used to reduce the number of test cases by identifying the ones that are most likely to uncover defects.

Understanding Bugs and Defects

In the realm of software testing, bugs and defects are anomalies or irregularities in the software that cause it to behave unexpectedly or incorrectly. A bug is usually a result of an error or mistake made in the coding or design of the software.

How to Document a Bug?

When a bug is discovered, it's important to document it properly for the development team to understand and fix it. A well-documented bug report should include:

• A unique identifier
• Bug severity and priority
• The affected software component
• Detailed steps to reproduce the bug
• Expected and actual results
