Integration testing is software testing where modules get logically integrated and tested as one complete system test. It aims to expose any defects, bugs, or errors in the interaction between these software modules, while emphasizing on the data communication between various modules. Thus, it’s also known as “I & T” (Integration and

For me integration testing means testing how multiple microservices integrate to eachother and facilitate a user-workflow. With the goal of finding configuration and wiring issues. For me contract testing means testing a single microservice API. Testing inputs and outputs of a single service to see if it meets its documented contract.

For functional testing, the core focus is on customer requirements, and the application is tested to see if they are met. As for non-functional testing, the focus is on validating the customer experience for the application. As a result, non-functional testing considers customer feedback a critical driver of test case planning and covers

Functional testing: the process of quality assurance of a product that assumes the testing of the functions/functionalities of component or system in general, according to specification requirements. E2E testing : it needs for identifying system dependencies and ensuring that the right information is passed through multiple components and systems.

Functional testing is a type of software testing where the basic functionalities of an application are tested against a predetermined set of specifications. Using Black Box Testing techniques, functional tests measure whether a given input returns the desired output, regardless of any other details. Results are binary: tests pass or fail. Unit tests or small tests only verify a very small portion of the app, such as a method or class. End-to-end tests or big tests verify larger parts of the app at the same time, such as a whole screen or user flow. Medium tests are in between and check the integration between two or more units. Figure 1: Test scopes in a typical application.
There are three general categories of tests: functional, non-functional, and maintenance. In addition, these categories have subcategories encompassing several testing techniques. In particular, we’ll explore unit and integration tests that belong to the functional testing category. 3. Unit Testing
Module #1: This is the search box visible to users where they can enter text and click the search button. Module #2: It’s a converter or in simple terms program which converts entered text into XML. Module #3: This is called Engine module which sends XML data to the database.
Integration Testing is performed to check the effective functionality of the units between each other. Regression Testing is done to check if old bugs have been reintroduced to the system after code modifications take place. Integration Testing is normally done before the initial deployment of the application.
Non-functional testing is as important as functional testing. Below is the difference between functional and non-functional testing: It verifies the operations and actions of an application. It verifies the behavior of an application. It is based on requirements of customer. It is based on expectations of customer. System testing is a testing level in which tests are performed to know if a complete build aligns with functional and nonfunctional requirements made for it. In contrast, Integration testing is a testing stage where two or more software units are joined and tested simultaneously. The real challenge is understanding the full range of conditions

Difference between Performance testing and Functional testing: Verifies that software functions as intended and meets specified requirements. Evaluates the system’s performance under various conditions like load, stress, and scalability. Tests individual functions or features to ensure correct behavior.

\n difference between functional and integration testing
Integration testing is black box testing. 5. Unit testing is performed by the developer. Integration testing is performed by the tester. 6. Detection of defects in unit testing is easy. Detection of defects in integration testing is difficult. 7. It tests parts of the project without waiting for others to be completed. Functional testing, on the other hand, involves black-box testing. Unit testing is often done at the start of the development. Unlike unit tests, functional tests are conducted only after building the functions. Since unit testing is easier and simpler to write and execute, its cost is lower than functional testing. SK5l2.
