Types of Software Testing

Hiring applicable software testing services is a wise investment for any company’s IT infrastructure. Not only does it ensure quality over programs or websites, but it also allows bigger savings because it limits possibilities of bugs and software errors. If you are planning to invest in software testing services, you might as well review the types of software testing for your reference.

There are four types of testing that can be incorporated during quality control and software testing:

  • Functional testing – to detect functional defects in the system
  • Performance testing – to detect system defects when it is not performing according to the requirements
  • Usability testing – to detect system defects when errors occur based on the end user
  • Security testing – to detect security defects on the system

On the other hand, there are two software testing methods namely:

Manual Testing – this is the oldest method wherein the development team identifies the error and then executes the solution

Test Automation – This applies automation in the system in detecting errors in test case management, bug detection, and execution of test cases.

The software testing cycle explains the flow of the testing procedure. The most used and trusted model of testing cycle is the Verification and Validation Model. Below is the software testing types available in the market:

Black Box testing – also known as the behavioral testing, it is the process of giving input to the system and then checking the output without investigating how the system generates the output

Functional testing – this type of testing checks whether the system is running according to the specified functional requirements

Performance testing – this checks whether the system is performing properly using the Load and Stress Testing applied internally and externally

Usability testing – this tests whether the overall system is in accordance with the desired usage of the program

Regression testing – this checks all the components and whether changing any of it will affect the function as a whole

Smoke testing – it is also referred to as Build Verification Testing or Link Testing that aims to determine whether the software is ready for testing without going back to the smallest components

Sanity testing – checks for the entire behavior of the system. It is also called Narrow Regression Testing

Parallel testing – checks the system using two different methods and then comparing the results

Recovery testing – this measures how fast the system will recover in cases of breakdown or corruption

Installation testing – this identifies which part of the installation process affects the system correctly or incorrectly

Compatibility testing – this checks whether the system is compatible with different types of hardware and software

Compliance testing – this identifies whether the system complies with the standards set by governing authorities

Exploratory testing – this subjects the system to ad hoc testing to check other possible features

User interface testing – this tests whether the system is user-friendly

Unit testing – this test is done in the manufacturer’s area to confirm if the unit is operating efficiently
