Automated Integration Testing Services

Many software products require contact with other systems and modules, thus it’s critical to understand how these modules are connected and confirm that they’re working properly. This is something that QAonTOP can assist you with.

QAonTOP Advantages

Advantages of integration testing with QAonTOP


Testing to define interface issues

Examine the project’s interfaces to identify and fix 100% of the problematic fragments and controls. Work to improve system interactions and data exchange.


Client oriented

Apply customer experience by using the most common models and interactions to identify key problems and address them effectively.


Start instantly

We don’t wait for development processes to finish, launching QA early in the project. This allows us to track problems faster and delegate fixes to colleagues.


Ensuring modules interaction

We check for compatibility of all elements of the complex, excluding artifacts or errors in the work from the first to the last stages and cycles.

Integration testing services we provide:

When you hire a integration testing organization, you’re almost certainly signing a long-term contract. We start with the first implemented feature and work our way through the app’s completion and the first user. Today is a free consultation. Let’s discuss our cooperation!

Bottom Up

We test the lower level modules first, then those on the way to the top of the hierarchy. This method necessitates the readiness of all constructed modules at all levels of the system and permits testing findings to be used to determine application readiness.

Top Down

Top Down approach starts with high-level modules and works its way down, ensuring that basic functionality is only verified at the end of the cycle. Low-level modules are replaced with stubs, which are later replaced by genuine active components.

Big Bang Integration Testing

When all of the components have been developed, we combine them and test the communication in the resulting system.

Incremental Integration Testing

We begin by verifying the communication between a few conceptually connected components, and as each test is successfully performed, we add new ones.

Integration Testing Input and Output Parameters

Regardless of the type of project, there is a strictly defined set of I/O criteria for integration QA.

Input parameters:

Elements that have successfullypassed modular QA.
Key problems solved.
Correct format of data and components.
Project roadmap, work plan.
Deployed test environment.

Output parameters:

Integrated component is 100% functional.
Cases are documented.
Defects fixed and displayed in reports.

Work scenario and related recommendations

Prioritize your work and prepare a plan for the proper deployment of the QA process. Prepare scripts and environments to run, monitor, and track errors.Identify the main components and assign them the highest priority when distributing QA tasks among team members. Control their implementation by launching them in the shortest possible time.Ask for the project’s technical documentation and organize the creation of scenarios based on it.

Take maximum responsibility for this process, detailing cases and specifications. Additional components, such as modules or external integrations, also need to be thoroughly checked. Do not ignore them. Introduce as much data as possible to verify test cases and compare results to expectations.Use different sets of information to investigate project components more productively. Apply fictitious data and false values to identify non-standard problems in time.

Frequently Asked Questions:

Accordion Content
The overall testing of a whole system made up of several subsystem components or pieces is known as system integration testing (SIT). Hardware, software, hardware with embedded software, or hardware/software with human-in-the-loop testing may make up the system under test.
  • Big-Bang Integration Testing
  • Bottom-Up Integration Testing
  • Top-Down Integration Testing
  • Mixed Integration Testing
System testing is a type of testing that determines whether a full build meets all of the functional and nonfunctional requirements. Integration testing, on the other hand, is a step of testing in which two or more software units are joined and tested at the same time.

There are 4 approaches used:

  • Top Down Approach
  • Bottom Up Approach
  • Big Bang Approach
  • Hybrid Approach
