Whenever a company or team develops a project, they follow a proper method. They choose techniques based on the requirements and level of the project.
Like if the stakeholder has clear requirements, then the developer team can go for the waterfall model; if not, then the incremental model. Software testing methodologies and techniques are part of every software development technique.

Software Testing Definition
We can define software testing as running a program, or application to find bugs. Testing is the most common way to ensure that the finished product meets all the standards.
Purpose of Software Testing
- It Detects faults that the programmer has introduced during the development of the software.
- Increasing confidence in the level of quality and providing information about it.
- It eliminates flaws.
- To ensure that the final product fits the needs of both the business and the users.
- To gain clients’ trust by offering them a high-quality product.
Software Testing Process
The software testing process four components that are:
- Test Strategy and Test Plan: Every project needs a Test Strategy and a Test. You must have a Test Strategy and Software Testing Plan in place, regardless of the method your project uses. Make two separate papers out of them or combine them into one.
- Test Design: Test design is an aggregation of the Test Manager’s years of experience with previous projects, testers’ understanding of the system, and current testing procedures.
- Test Execution: One can execute the project in different ways, such as agile, waterfall, user acceptance test, and system integration testing. The test execution depends on the projects.
- Test Closure: Finally, the project ends after testing it using different methods and scenarios.
What are Software Testing Methodologies?
The many tactics or procedures used to test an application to verify it behaves and appears as we refer intended to as software testing methodologies. These include unit testing, system testing, front-end testing, and back-end testing.
Types of Software Testing Methodologies
1) Agile Testing Method
Agile software testing approaches have series of brief iterations known as sprints. Small working groups oversee them and consider new testing requirements.
Planning, requirements analysis, and testing are steps of each sprint. The testing team thoroughly tests every project release. This ensures that it addressed any system bugs before the next release.
- It allows the team to change the project at any moment to ensure that it meets the criteria.
- This method of progressive testing reduces risks.
- The only disadvantage of this method is that constant client involvement puts additional time pressure on all parties involved.
2) Waterfall Method
The base concept of the waterfall method is a team’s step-by-step advancement through the testing process. The team documents and plans the entire project, and then the team of testers take small steps to make progress.
Developers must complete each step before proceeding to the next. For example, as soon as the software design is complete, then the team will begin executing test cases to confirm that the built program behaves as planned.
- This method of software testing is relatively easy to plan and manage.
- It cannot implement immediate changes and new requirements. So, this method is not suitable for projects where the requirements change.
3) Incremental Method
Multiple iterations make up the incremental testing procedure. This method breaks down the project into smaller components. Each of which follows several waterfall model iterations and improves the product by adding additional features.
- The benefit of iterative development is that test feedback is immediately available at the end of each cycle.
- The discussion about feedback on deliverables and effort at the end of each increment increases communication overheads.
4) Spiral Method
It has also made up of cycles that repeat themselves. Planning, risk analysis, engineering, and final review are the four steps. When the previous cycle ends, the next one begins.
In addition, teams receive instant test feedback at the last step of each cycle, ensuring that the product’s quality remains high.
- Testing teams can use this model to identify mistakes and their reasons.
- Minor projects cannot afford the spiral model.
- It does not have a fixed timeline.
5) Extreme Programming Method
Extreme programming is an agile method that emphasizes rapid development cycles. It groups simple engineering activities into a project. Programmers create a simple piece of software and then provide feedback to the consumer. It considers the customers’ feedback, and the engineers move on to the next part of the project.
- The team thoroughly reviewed every line of code, this approach helps teams to produce high-quality code.
- Customers who have a hazy software design in mind could use extreme programming.
- Meetings between the software development team and clients increase the time required.
Software Testing Techniques
1. Ad hoc Testing
Ad hoc testing tests out the project with no paperwork or planning. It frequently tests at random, with no pre-determined technique or goal in mind. The purpose is to find flaws in the application and break them by executing the flow or a random function.
2. Agile Testing
A type of testing that guarantees that follows Agile Software Development Manifesto’s ideas.
3. Black box Testing
This is the testing of the complete system by people who do not know the software’s design, structure, or implementation. It checks bugs in the user interface, performance, behavior, data structures, and functions.
4. White-box Testing
This is comparable to Black Box testing; however, the tester is aware of the software’s design, structure, and implementation.
5. Gray box Testing
A type of testing that combines the two ideas of black box and white box testing. Some aspects of the item’s design, structure, and implementation are familiar to the tester, while others are not.
Some people get confused about what are software testing methodologies and techniques. Every software development model has a testing phase in it, so you can consider that as a software testing method as well.
The software testing has different other ways like Ad hoc testing, white box testing, you can take them as both; software testing types and software testing techniques.
