What are the different types of Software Techniques?

We, as testers are aware of the various types of Software Testing Techniques such as Functional Testing, Non-Functional Testing, Automation Testing and their sub-types, etc.

Each of us would have come across several types of testing in our testing journey. Each type of testing has its own features, advantages and disadvantages as well. However, in this article, I have covered most promising types of software testing which needs to be executed for our respected project to make it success.

Let’s have a look.

Functional Testing types include:

  • Unit Testing
  • Integration Testing
  • Regression Testing
  • Smoke Testing
  • Alpha Testing
  • Beta Testing
  • System Testing

Non-functional Testing types include:

  • Performance Testing
  • Load Testing
  • Stress Testing
  • Volume Testing
  • Security Testing
  • Compatibility Testing

Unit Testing

It focuses on smallest unit of software design. In this we test an individual unit or group of inter related units. It is often done by programmer by using sample input and observing its corresponding outputs.

Integration Testing

The objective is to take unit tested components and build a program structure that has been dictated by design. Integration testing is testing in which a group of components are combined to produce output.

Integration testing is of four types: (i) Top down (ii) Bottom up (iii) Sandwich (iv) Big-Bang

Regression Testing

Every time new module is added leads to changes in program. This type of testing make sure that whole component works properly even after adding components to the complete program.

Smoke Testing

This test is done to make sure that software under testing is ready or stable for further testing. It is called smoke test as testing initial pass is done to check if it did not catch the fire or smoked in the initial switch on.

Alpha Testing

It is a type of acceptance testing which is done before the product is released to customers. It is typically done by QA people. (When software testing is performed internally within the Organization)

Beta Testing

The beta test is conducted at one or more customer sites by the end-user of the software. This version is released for the limited number of users for testing in real time environment
When software testing is performed for the limited number of people.

System Testing

In this, software is tested such that it works fine for different operating system. It is covered under the black box testing technique. In this we just focus on required input and output without focusing on internal working.

Performance Testing

This term is often used interchangeably with ‘stress’ and ‘load’ testing. Performance Testing is done to check whether the system meets the performance requirements. Different performance and load tools are used to do this testing.

Load Testing

The objective of Load Testing is to check how much load or maximum workload a system can handle without any performance degradation.

Load Testing helps to find the maximum capacity of the system under specific load and any issues that cause software performance degradation. Load testing is performed using tools like JMeter, LoadRunner, WebLoad, Silk performer, etc.

Stress Testing

In this we gives unfavourable conditions to the system and check how they perform in those condition.
(a) Test cases that require maximum memory or other resources are executed

(b) Test cases that may cause thrashing in a virtual operating system

(c) Test cases that may cause excessive disk requirement.

Volume Testing

The software or application undergoes a huge amount of data and Volume Testing checks the system behaviour and response time of the application when the system came across such a high volume of data. This high volume of data may impact the system’s performance and speed of the processing time.

Security Testing

System Testing is done to check how the software or application or website is secure from internal and external threats. This testing includes how much software is secure from the malicious program, viruses and how secure and strong the authorization and authentication processes are.

It also checks how software behaves for any hackers attack and malicious programs and how software is maintained for data security after such a hacker attack.

Compatibility Testing

It is a testing type in which it validates how software behaves and runs in a different environment, web servers, hardware, and network environment.

Compatibility Testing ensures that software can run on a different configuration, different database, different browsers, and their versions. Compatibility testing is performed by the testing team.

Final Words

This article explained several types of software testing. What kinds of tests you should run depends on the type of software you’re building and other factors.

There can be undetected errors in your application even after it’s launched, which will annoy the users and will cause problems for them. So automation of you project is very much needed. Tesbo is a good tool to perform end to end automation which helps you to measure the test coverage, it is fruitful to perform different kind of testing like Regression Testing, Smoke Testing, Alpha Testing and compatibility testing. Hence it proves that Tesbo is a magical tool which will really less down your efforts, give a try.

Happy Testing!!
