Software Testing Basics: Testing Types Explained

Security testing unveils the vulnerabilities of the system to ensure that the software system and application are free from any threats or risks. These tests aim to find any potential flaws and weaknesses in the software system that could lead to a loss of data, revenue, or reputation per employees or outsides of a company. Performance testing examines the speed, stability, reliability, scalability, and resource usage of a software application under a specified workload.

It ensures that the software product continues to work correctly after any changes or updates have been made. You need to know how the application will work in a variety of different conditions, and this is the purpose of performance testing. Performance testing can model various loads and stresses to assess the robustness of the application.

Proven Testing Solutions

For example, websites for pet insurance are being tested and you are purchasing insurance. Before conducting any thorough testing, a testing technique for this website confirms that all of these functionalities are operating as intended. This kind of software testing verifies the dependability of a software program and is carried out on the initial program build to guarantee that the program’s crucial features are operational.

It helps to identify bottlenecks in the system and improve the performance of the application. Security testing is a type of software testing that assesses the security of a software application. It helps to identify vulnerabilities and weaknesses in the system and ensure that sensitive data is protected. User acceptance testing is a type of acceptance testing that is performed by the end-users of the software system.

Types of Software Testing (100 Examples)

As the code becomes visible to testers, it is called clear box testing, open box testing, transparent box testing, code-based testing, and glass box testing. It tests whether a user can understand the application easily or not. The main advantage of usability testing is to identify how long it takes to complete the tasks. Is performed to evaluate whether a component or system satisfies certain functional requirements.

  • To execute the exploratory testing, we will first go through the application in all possible ways, make a test document, understand the flow of the application, and then test the application.
  • It involves testing the website’s functionality, performance, and user interface on different web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera, among others.
  • Whenever we are done with the unit and integration testing, we can proceed with the system testing.
  • Another subset of acceptance testing, alpha testing uses internal team members to evaluate the product.
  • Regression testing is one of the most important steps to take before an application can finally move to the production phase and it shouldn’t be skipped.

Non-functional testing is a combination of performance, load, stress, usability and, compatibility testing. In functional testing, all the components are tested by giving the value, defining the output, and validating the actual output with the expected value. The test engineer will check all the components systematically against requirement specifications is known as functional testing. Unfortunately, non functional testing is sometimes left to the end of the cycle. When it is overlooked or rushed, apps can be released with UX and performance issues.

Non Functional Testing

Multi-user load testing involves the parallel execution of tests on real devices on real networks to measure an authentic user experience. The goal of continuous testing is to test early and often to minimize business risk and maximize the quality of application released to end users. Single user performance testing checks that the application under test performs fine according to specified threshold without any system load. This benchmark can be then used to define a realistic threshold when the system is under load.

It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and resource usage. A smoke test is used as a build acceptance test prior to further testing, e.g., before integration or regression. Most software systems have installation procedures that are needed before they can be used for their main purpose. Testing these procedures to achieve an installed software system that may be used is known as installation testing.

V – Vulnerability Testing

Fonts and font sizes that are appropriate in the source language may be inappropriate in the target language; for example, CJK characters may become unreadable, if the font is too small. Globalization testing verifies that the software is adapted for a new culture . Today he runs the hugely popular Simple Programmer blog and YouTube channel, where he helps millions of developers every year to master the career and life skills that made all the difference in his success.

As we need the optimal amount of testing based on the risk assessment of the application. Globalization testing is used to make sure that the application will support multiple languages and multiple features. Testing the application randomly as soon as the build is in the checked sequence is known as Adhoc testing.

Acceptance Testing Planning

Different organizations are going to have very different ideas of how testing should be done and what process should be followed. Truly we’ve only scratched the surface of all the different types and classifications of testing. But, there is definitely some legitimacy to the idea of exploratory testing and perhaps I am a bit too harsh and judgmental.

Asking open-ended questions — such as what issues users run into while using the product and the type of features they would prefer to see — can help conduct testing from the user’s perspective. Creating test accounts in production systems that simulate the user experience is also a great way to incorporate their feedback for successful software testing. This type of automated testing is performed on every piece of software a developer delivers. It offers error detection and validation of code early in the process.

The 2023 State of Test Automation

This JavaScript example uses the Supertest library to make HTTP requests to an application we’re testing. Often, you will perform gray box testing during the testing phase of the SDLC. The following example of non-incremental integration testing uses JavaScript, the Mocha.js testing framework, and the Chai assertion library. The company performs cross-platform testing to ensure that the software works correctly on different operating systems such as Windows, macOS, and Linux.
