Types of Software Testing - Techniques, Tools & Best Practices

Software testing can save businesses up to 30% in development costs with early issue identification. 

It has become a business to ensure that the quality of the software is of the top notch. The only way possible for the same is through proper software testing implementation in different phases of Software Development Life Cycle. 

There are different types of software testing that needs to be worked on to keep things right in terms of quality and functionality of the application. If you are thinking about how to work on the different types of testing, then we have it all answered for you below. Read on. 

Software Testing: Brief Synopsis

The practice of assessing a software application to make sure it satisfies certain criteria and operates properly is called software testing. The main goals are to find flaws, make sure the program meets user expectations, and confirm compliance with technical criteria. Below we highlight some of the essential value software testing brings into play. Check it out:

1. Cost Efficiency: Early detection of defects reduces costs associated with post-deployment fixes.
2. User Satisfaction: Thorough testing ensures a positive user experience, leading to higher customer retention.
3. Risk Mitigation: Identifying potential failures before launch minimizes risks associated with software failures.

Types of Software Testing

Any software development company will always work on different kinds of software testing to check the product from all angles. Below we have classified the different testing techniques that are primarily taken into consideration. Check it out.

1. Manual Testing

Manual testing is the process of human testers running test cases unassisted by automation technologies. Exploratory, usability, and ad-hoc testing depend on it.

Key Techniques in Manual Testing

A. Exploratory Testing

In exploratory testing, testers actively investigate the application ignoring predefined test cases. This approach lets testers have a more flexible and adaptive testing process by encouraging them to use their intuition and experience to find problems. It is especially useful for finding unanticipated flaws and understanding user interactions with the product.

B. Usability Testing

Usability testing emphasizes assessing the user experience and interface design of the software. The aim is to evaluate how simply people can use the app and finish activities. Testers can find areas for improvement by seeing actual customers interact with the software, so guaranteeing the product is intuitive and user-friendly, which finally improves general consumer happiness.

C. Ad-hoc Testing

Lacking organized documentation and set test cases, ad-hoc testing is an informal testing method. Without using a particular approach, testers find flaws by means of arbitrary inspections. This adaptable approach can identify problems that traditional testing could overlook and enable fast evaluations. Often as a supplement to more organized testing techniques, ad-hoc testing is beneficial for confirming function in a less demanding way.

2. Automated Testing

Automated testing runs test cases using certain software. For performance, load, and regression testing, it is efficient.

Key Techniques in Automated Testing

A. Unit Testing

Unit testing emphasizes testing single parts or functions of a software program to verify they operate as intended. Usually done by programmers, this approach enables early identification of code flaws. Teams may guarantee that the building blocks of the application are dependable and operate properly before integration by verifying each unit in isolation.

B. Integration Testing

Integration testing assesses the relationships between integrated components or modules of a software program. The main objective is to find interface problems that could result from distinct units cooperating. This testing stage guarantees proper data flow between modules and correct operation of coupled features, hence producing a more coherent and functional system generally.

C. System Testing

System testing is the process of assessing the whole integrated software system to make sure it satisfies certain criteria. This thorough testing stage evaluates the application's general functionality, performance, and user expectation compliance. Teams can verify that all parts interact harmoniously before the product is delivered to end-users by validating the whole system in a simulated production environment

Comparison of Manual and Automated Testing

Software Testing Techniques

1. Functional Testing

Functional testing focuses on verifying that the software operates according to specified requirements. It includes:

• Black Box Testing: Testing without knowledge of internal code, focusing on inputs and expected outputs.
• White Box Testing: Testing with knowledge of the internal code structure, ensuring all paths are tested.
• Gray Box Testing: A combination of black and white box testing, assessing both functionality and internal workings.

2. Non-Functional Testing

Non-functional testing evaluates aspects of the software that are not related to specific behaviors or functions, such as performance, usability, and security.

• Performance Testing: Ensures the software performs well under expected load conditions.
• Load Testing: Tests how the software behaves under heavy load.
• Stress Testing: Evaluates how the software performs under extreme conditions.

3. Regression Testing

Regression testing is crucial after changes or enhancements to ensure existing functionalities remain unaffected. This process typically involves re-running previous test cases.

4. Acceptance Testing

Acceptance testing determines whether the software meets the acceptance criteria and is ready for deployment. This type often involves direct user feedback.
