Functional testing primarily focuses on whether the system delivered the output desired. Non-functional testing validates the “hows” of the AUT’s features, performance, security, scalability, etc. Functional testing can be considered as one of the most common and foundational types of testing. When people refer to “testing” in a general context, they often have functional testing in mind. In most cases, multiple sets of values or data are used to test the same functionality of a particular feature.

This helps streamline the testing process and ensures resources are used efficiently. To create an effective test plan for component testing, it is important definition of component testing to focus on assessing the requirements provided by the users or clients. The goal is to develop a complete testing strategy to meet all requirements.

The Test Pyramid Part 4: API / Component testing

Unlike module testing where the single component/module is tested thoroughly before integrating it to other components. So we can say that Component testing is performed before Integration testing. For example if you have website which has 2 page registration process.

The related load testing activity of when performed as a non-functional activity is often referred to as endurance testing. Volume testing is a way to test software functions even when certain components (for example a file or database) increase radically in size. Stress testing is a way to test reliability under unexpected or rare workloads. Stability testing (often referred to as load or endurance testing) checks to see if the software can continuously function well in or above an acceptable period. Non-functional testing refers to aspects of the software that may not be related to a specific function or user action, such as scalability or other performance, behavior under certain constraints, or security.

Installation testing

Component Testing is a type of software testing in which usability of each individual component is tested. Along with the usability test, behavioral evaluation is also done for each individual component. To perform this type of testing, each component needs to be in independent state and also should be in controllable state.

With the advent of modern continuous deployment practices and cloud-based services, the cost of re-deployment and maintenance may lessen over time. While automation cannot reproduce everything that a human can do (and all the ways they think of doing it), it can be very useful for regression testing. However, it does require a well-developed test suite of testing scripts in order to be truly useful. Security testing is essential for software that processes confidential data to prevent system intrusion by hackers.

The same practices are commonly found in other development models, but might not be as clear or explicit. There is little agreement on what the specific goals of performance testing are. The terms load testing, performance testing, scalability testing, and volume testing, are often used interchangeably.

While indeed accounting for a major part of any test plan, functional testing should not be the only testing type your team performs. Non-functional testing is the much needed counterpart to functional testing, and it nicely covers what functional testing misses. Testing for internationalization and localization validates that the software can be used with different languages and geographic regions. The process of pseudolocalization is used to test the ability of an application to be translated to another language, and make it easier to identify when the localization process may introduce new bugs into the product. This is a combination of a React component with a set of wrappers that allow the Next.js build and runtime process to supply static and dynamic data as props. At first, such restrictions might sound draconian, but they generate interesting and valuable results.

Since they are designed to focus on small targeted behaviors, component tests are easier to write, simpler to maintain, and faster to execute which makes them ideal to add to an iterative development workflow. By design, some Next.js code runs in-browser (such as most React components) and some code runs server-side (such as API routes and data hooks). To accurately assess code coverage, it’s important to understand this division of client- and server-side code. Component tests primarily focus on in-browser code, while e2e tests cover full-stack code.

• This step is essential for testers to learn the function’s purpose and how users would approach it.
• After the entire component has been completed, the test engineers or QA team conduct the component tests.
• Login pages are designed based on user levels like personal and business access.
• These small parts are called units, hence the name “unit testing.” In unit testing, you verify that the units work correctly, in a way that’s independent both from other units and from external concerns.
• As opposed to Unit testing executed by the development team, the Component/module testing is executed by the Testing team.
• Along with the usability test, behavioral evaluation is also done for each individual component.

In this case, functional testing simply is used to check if the Login page is working as expected. The SRS can be validated statically by consulting with the stakeholders. Nevertheless, running some partial implementation of the software or a prototype of any kind (dynamic testing) and obtaining positive feedback from them, can further increase the certainty that the SRS is correctly formulated. A test plan is a document detailing the approach that will be taken for intended test activities.
