Types of Manual Testing | Basic Concepts & Explanation

Manual Testing

It is a type of software testing that involves the use of a human to verify the correctness of a system. Manual testing can be a fun and interesting way to learn. It's also a good way to learn about the software you are testing, as well as how it works and how it should work. 

Testing should be easy to follow with clear instructions on how to perform each step in your test plan, so you don't waste time repeating yourself or asking questions later on when it's too late in the process. Manual testing is a process that involves the following steps:

• Understand the need for testing.
• Identify what type of testing you'll do (unit, functional, integration).
• Define your test plan for each phase of your project's lifecycle (e.g., design, development, QA).

The primary goal of manual testing is to verify the correctness of the software system.

This means that a tester should be able to identify bugs, explain how to fix those bugs, and explain how to avoid those same bugs in future releases. Manual testing involves following a certain procedure. The main purpose of manual testing is to identify defects, which are bugs and errors in the software. Here are some benefits of following this type of testing:

• It's more thorough than other types because it involves more details about how things work and what they do.
• You can see where you should be spending your time and effort, which will help you know if there's anything else that needs to be done after completing this step or not doing so at all (e.g., fixing bugs).

A tester can read the code of the program to identify bugs.

The tester reads and understands the code, ensuring that they know what each function does as well as how it operates and interacts with other parts of your application. They do this by going through it line by line, making sure they understand how each function works before moving forward with testing and fixing any issues found during their review process.

They also verify that bugs are fixed using automated testing tools such as Selenium Webdriver or headless browsers like PhantomJS (which allow them to access directly into your server). This ensures that all critical issues within your code base have been resolved before committing anything back into production so that further development on future versions is seamless from start to finish.

Types of Manual Testing

Manual testing can be implemented in certain ways:

Black Box Testing

Black box testing is the most common type of manual testing. This means that you don't have to know how your software works, but rather focus on testing how it behaves when given certain inputs. Black box testing can be used for all types of software, including web applications and desktop applications. For example, if you're thinking about building an e-commerce website and want to make sure it doesn't crash when people add items to their shopping cart or try out different payment methods (like PayPal), then black box testing would be useful for checking those things out—you just need to make sure that they pass basic functionality tests while they're loading up their carts with items.

White Box Testing

White box testing is a type of software testing that is based on the concept of "don't look at the source code". This type of testing focuses on analyzing and verifying the functionality of a system by using only its external interfaces. White box tests are performed by:

• Analyzing and understanding your application's requirements.
• Developing test cases for each requirement, then executing them against an environment that represents your actual production environment (e.g., virtual machine or physical hardware).

Unit Testing

Unit testing is the testing of individual units of source code. It is a form of unit test, which means it tests each unit individually and not as a whole system. Unit tests are often used to verify that individual classes or methods work correctly, but they can also be used for integration testing (testing two or more units) and system testing (testing an entire application).

System Testing

It is a type of testing that involves testing the entire system as a whole. In other words, it's not just about running a particular test on one or two parts of your application—it's about running all of them at once.

System testing can be used to test everything from the hardware through to your data model and logic flow. It's especially useful when you're writing more complex applications where many moving parts need to work together correctly to provide a good user experience (UX).

Integration Testing

Integration testing is a type of software testing that checks the interaction between modules or components of a system. Integration testing is performed by using a combination of unit testing and system testing. Integration tests are usually used to verify that all the modules work together correctly, but they can also be used to test if only one module works as expected (such as when upgrading).

Wrapping up:

This blog post went through the basics and types of manual testing. It is a vital part of user-friendly software development because humans are involved in testing software applications and end-users are also humans. Manual testing requires patience, creativity, and an open mind.
