What Kinds of Tests do a Functional Testing Company Offer its Clients?

Software testing enables delivering a seamless, stable, working application to the ultimate users. Therefore, the need for a functional testing service arises when you focus on testing the primary application functionalities against predetermined specifications.

You describe user expectations, actions, and results after using the product to determine the quality of its functionality. Functional testing utilizes black box techniques that give either pass or fail binary results.

Conducting functional testing QA is critical to ensure to deliver the crucial expected outputs to the end user. Even if the application performs well in the non-functional testing, failing the functional tests means it is not working.

Now that we know its significance and what it entails, let’s dive into the testing areas covered under manual QA testing:

Areas to Test in Functional Testing

Since functional testing concentrates on the crucial aspects of the application’s functionalities, these get divided into the following categories:

1. Accessibility

Accessibility checks get conducted to verify meeting these requirements. It refers to making web and mobile apps usable for all, including people with disabilities.

2. Usability

It involves testing the seamlessness through which users can navigate the website and application.

3. Error Alerts

Since technical things aren’t free of bugs and errors, they must show the appropriate code and message to indicate the presence of a particular error. The manual testing services aim to validate the system’s functionality and accurate bug descriptions.

4. Primary Functions

Without main functions working well, there’ll be no product to give users. Therefore, manual QA testing for seamless functioning is critical to offer value to customers.

Various Types of Functional Testing

Based on the different areas targeted in API functional testing, the following are the broad categories of different types of testing:

1. Unit Testing

Under unit testing, the manual testing companies check every code in a particular component matches the predetermined output. Usually, the developers focus only on the interface and component specification.

Every unit of one code of a particular component gets tested standalone. The code documentations get prepared with the progress details before proceeding to the next unit. Since it's covered into small parts to verify the inputs and outputs, it is quicker to execute and verify its functionality.

Unit testing indicates the code is most likely to break. Without manual unit testing, the following issues are bound to appear:

• Challenging to diagnose failed tests
• Fixing tests around the known issues but not carrying out actual diagnosis and treatment

2. Smoke Testing

Smoke testing is critical to ensure the essential aspects of the application work as intended. Also known as build verification testing, the functional testing company uses it after releasing each build and checks its stability.

It is not supposed to be exhaustive but definitive of the critical system’s functionality. Moreover, since only basic operation levels are tested, progressing to detailed testing is not necessary.

3. Integration Testing

Your system components and modules might have passed their tests independently. However, cross-browser testing manually ensures whether they work together perfectly or break down.

When the components depend on each other for functioning, integration testing shows bugs that could hinder its functionality. Therefore, it becomes a critical part of manual mobile testing.

4. Regression Testing

When you add new codes to your application, regression testing ensures the quality doesn’t take a hit or “regress.” These tests dive into the latest code additions and check if they break existing functionalities. It verifies that the changes made do not harm the stability and functionality of the application.

In simple words, regression testing verifies no new bugs got added to the build, and the earlier ones remain dead. Several functional testing tools prove their value in regression testing.

5. Sanity Testing

A cousin to smoke testing, sanity testing verifies the basic functionalities and helps avoid detailed testing of broken software. Instead of running the minor modifications through regression testing, the manual testing services perform sanity tests.

Sanity testing only focuses on the new changes compared to smoke testing, which considers end-to-end functionalities. Moreover, smoke testing begins from initial unstable builds, whereas the opposite is true for sanity testing.

6. User Acceptance Testing

Under this testing scenario, the product is given to a limited group of actual users for use in the production environment. It allows real users fresh perspectives about bugs the internal QA team missed. Therefore, before launching fully, proper modifications can turn the product into a success story.

Summing Up

Mobile app manual testing is critical to bridge the gap between a business’s expectations of the end user’s requirements and the actual user’s needs. The list of different types of functional testing is long but covers every aspect of software’s usability, accessibility, functionality, and error-free conditions.
