What is an automated test tool?
Just as a physical product is tested to check to see if it meets the desired behavior and specifications, software is also tested. Software testing can manually perform people or by tools. An automated test tool is a piece of software used to test the target software, ie the software considered. Such a tool performs various target software tests and determines whether the tests are successfully sold.
The software needs to be tested to ensure that the correct results are generated, valid inputs are accepted and properly processed and invalid inputs are rejected. Testing is essential to determine whether the results are generated quickly, the software works well, even if a large number of people approach it simultaneously, etc. Manual tests are often used, but they are dependent on the thoroughness of people performing testing. Test software takes time and requires a significant number of people for most non -trivial applications contributes to costs. In addition, the testo cannot beVan on thousands of contemporary users or large data volumes easily performed in a manual way.
Test automation is the use of tools to test software. The automated test tool is itself a software that can be developed, purchased or obtained. The tool usually starts to perform target software and transmits different inputs to the target software to test different conditions. It evaluates the corresponding target software outputs and monitors the result of the pass/failure of each test. At the end of a series of tests, this tool usually provides summary results, so a person can quickly determine the number and severity of the defects.
Automated test tool can work in two ways. First, it can be controlled by a code, a tool that can be closely related to a written code to check that the results for varioameric inputs are correct. Secondly, it may be based on a user interface,Where users' activities, such as mouse movements, keyboard inputs, voice inputs, etc. are imitated.
On the market, there are tools for automatic testing of general purpose. Most of them are quite expensive, but some tools are available for free. If the target software is highly specific or unique, then the test tool must probably be developed in the software team itself. As with all software, the tools themselves have limitation and work correctly only when good input data is provided. If one does not imply a relatively complete set of tests, the tool does not help determine the quality of the target software.
The automated test tool has many advantages. A number of tests are created once, the tests can be performed faster than a person can perform. Tests can be performed PEars night or in odd hours, so people free to focus on what they do best. Tests can be carried out again and again to determine whether errors have been crawled into the target software because they are adjusted over time.
