Advantages of integration testing with Zappletech

Testing to define interface issues
Examine project interfaces to identify and fix 100% of problematic fragments and controls. Work to improve how systems interact and share data.
Apply the customer experience by using the most common models and interactions to identify the key issues and how to address them in an effective way.
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.
Ensure module interaction
We check the compatibility of all complex elements, eliminating artefacts or errors in the work from the first to the last stages and cycles.

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 system levels 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
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 successfully passed 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:

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
