Automated testing is
a process to validate that software functions appropriately and meets
requirements before it is released into production. This form of software
testing uses scripted sequences that are executed by testing tools.
An organization can
apply automated checks to a broad range of test cases, such as unit, regression
and API testing. Automated software testing's main benefit is that it
simplifies as much of the manual effort as possible into a set of scripts. If
unit testing consumes a large percentage of a quality assurance (QA) team's
resources, for example, then this process should be evaluated as a candidate
for automation. Automated testing tools execute tests, report outcomes and
compare results with earlier test runs.
Automated tests can
run repeatedly at any time of day. This approach fits in with continuous
testing as well as continuous integration and continuous delivery (CI/CD)
software development practices, which aim to shuttle code changes to production
without gates that require manual intervention.
Benefits of automated testing
Automated testing can
boost a QA team's efficiency. Some benefits include higher accuracy as well as
better reporting capabilities, coverage, resource efficiency, bug detection and
reusability.
When a software
tester manually checks a system, he can make a mistake, especially when an
application contains hundreds or more of lines of code. Automation helps the QA
team avoid these application testing mistakes and executes checks in a faster timeframe
than a person.
Some test automation
tools have reporting capabilities that log each test script to show users the
status of each test. A tester can then compare the results with other reports
to assess how the software operates compared to expectations and requirements.
Automated testing
enables staff to avoid manual tests and focus on other project priorities. A QA
team can reuse automated test scripts to ensure each check executes the same
way every time. Additionally, automated testing helps a team quickly find bugs
in the early stages of development, which can reduce overall working hours.
