What is integration testing?

Integration testing is the phase of the development and testing of the software in which multiple units or modules are connected and tested in the configuration of the program or hardware. All these different units were usually tested individually to ensure that each unit works properly; This testing phase integrates these disparate units into a larger system. This can be done in software development to ensure that different aspects of a larger program are able to work together or test hardware to ensure the correct function between different units. Integration testing is a key testing phase as many errors can be found and versions of timely release of total software or hardware can be developed. The first phase is called units testing and is focused primarily on testing individual units or parts of a larger program or system on the enjojezing that each unit works in itself. These separate units are connected when testing integration as soon as each passed through TESBy tieing units to ensure that they can cooperate in larger groups. They will then usually be assembled in a full system or program that develops and tested as part of this complete system called system testing.

There are many ways to test integration, although some common methods are usually used. Testing from bottom -up is quite common and usually includes testing different aspects of the integrated system starting with lower system levels. As soon as these "lower" aspects of the system test, testing moves "up" to more important aspects. It is also possible to perform a form of integration testing from top to bottom, in which the highest levels of the system are first tested and the process continues to move down to low levels.

One of the main problems with these two types of integration testing is that neither of them can easily create inEarly release of the product with basic functionality. This type of version of the alpha version can be vital for greater testing opportunities, and therefore other approaches must usually be accepted to make such relaxation. One such approach is the form of "Big Bang" testing, in which all parts of the integrated system are tested simultaneously. This may be advantageous if there are few problems or mistakes with the software tested, but it may be difficult to determine specific problems if too much is present.

There is also a type of integration testing known as "sandwich testing" that seeks to alleviate some of these problems. In principle, this type of testing starts at the same time by testing from top and bottom top and both forms of testing effectively "meet the middle". This allows timely testing of basic logical systems, perk testing from top to bottom and identifies minor problems earlier, as with bottom -up testing. Such testing can also produce a PR version fasterSummer of timely edition for multiple testing in the extent or preliminary demonstration of the media product.
