Software testing should follow a "pyramid" approach wherein most of your tests should be unit tests, followed by integration tests and finally end-to-end (e2e) tests should have the lowest proportion. [6] [7] [8]
System testing describes testing as at the system level to contrast to testing at the integration or unit level. System testing often serves the purpose of evaluating the system's compliance with its specified requirements [citation needed] – often from a functional requirement specification (FRS), a system requirement specification (SRS ...
Integration testing, also called integration and testing, abbreviated I&T, is a form of software testing in which multiple parts of a software system are tested as a group. Integration testing describes tests that are run at the integration-level to contrast testing at the unit or system level.
Exchange to exchange (sometimes Exchange-to-exchange, abbreviated E2E) is integration, between certain pairs of computer systems. To qualify as E2E, each of the paired systems must have a primary use of acting as an exchange , or gateway, among its own customers.
System integration testing (SIT) involves the overall testing of a complete system of many subsystem components or elements. The system under test may be composed of electromechanical or computer hardware, or software , or hardware with embedded software , or hardware/software with human-in-the-loop testing.
The term "end-to-end encryption" originally only meant that the communication is never decrypted during its transport from the sender to the receiver. [9] For example, around 2003, E2EE has been proposed as an additional layer of encryption for GSM [10] or TETRA, [11] in addition to the existing radio encryption protecting the communication between the mobile device and the network infrastructure.
The tester is focusing test suite generation on what is most important, testing the functionality of the system. When manually creating a test suite, the tester is more focused on how to test a function (i. e. the specific path through the GUI). By using a planning system, the path is taken care of and the tester can focus on what function to test.
The measurement paradigm is to assess degradations of a decoded video sequence output from the network (for example as received by a TV set top box) in comparison to the original reference picture (broadcast from the studio). Consequently, the setup is referred to as end-to-end (E2E) quality testing.
