Test Automation 101: What Is Automated Testing and How Does It Work?
Do you know why many developers are jumping on the automation bandwagon? In this post,Guest Posting we?re going to have a look at the basics of automated testing. We?re going to look at manual testing aswell, and how it compares and complements automated testing.

But, first let?s learn: what's automation testing?

Test Automation: What It Is and What It?s Not
Basically, test automation is the usage of automation tools or platforms to greatly help testers and developers test software products. It involves the development and execution of test scripts that automate a development team?s testing efforts. Automation tools are also developed to assist with report creation and results analysis.

You can automate both functional and non-functional software tests. It is possible to automate more than just unit, integration, smoke, regression, and performance tests. It won?t make sense to automate some recent tests though, so how do you know when to automate and when not to?

When and When Never to Automate
A test must only be automated when it meets certain criteria, otherwise, it wouldn?t make sense and manual testing would still be the easiest way to go. Whenever choosing which tests to automate, here are some things you need to consider:

Is the test repeatable?
An automated test will only save you time, money, and effort if it?s repeatable. If not, then you?re likely to just spend more resources writing the test script than manually performing the test itself. A repeatable test follows three basic steps: setup, execution, and tidy up.

Is the test objective?
If a test requires human opinion or user feedback subsequently, it can't be automated. An example will be a beta test. Beta tests are performed by real users in real environments. The results of the tests are real user feedback on the quality of the system.

May be the test time-consuming to run?
Here are some examples of time-consuming tests:

tests that has to capture images for recording and validation purposes
tests that involve large amounts of input data
tests that need to be run in multiple configurations (such as for example different OS and browsers)
These aren?t the only criteria for choosing which tests to automate though. Your choice to automate sometimes depends upon the pace with which your team is developing a product. Sometimes, it depends on the merchandise?s development stage. Ultimately, automating your tests be determined by far more factors than just knowing which tests make sense to automate.

Automation Testing Myths and Misconceptions
There are always a ton of myths and misconceptions about automation testing. In the event that you?re only starting to consider automation, then it?s best to get these misconceptions out of the way as soon as now. Here are a few of them:

Test automation offers you more free time
Test automation can help you save time, and money, and a lot of effort, for example. But, we can?t actually say that it?s leisure time. Let?s compare.

Once you?re manually testing something, you have your tests and your test cases. As long as you know how to perform these tests and you understand what needs to happen, you?re ready to go. Usually, however, these tests are repetitive and take a long time to perform.

But, with automated tests, you?re going to set aside time to code your test scripts beforehand. But, enough time spent actually performing the test is greatly reduced. Now, you don?t have to spend time manually testing the product again and again. You can just run your automated tests and focus your efforts on improving your test scripts or other more important tasks.

Test automation is expensive
Or, is it? Investing time, money, and effort into automating your tests is generally advisable. Most developers find that test automation tools can just about pay for themselves in a year or two. You can create usage of free test automation tools and platforms to even lower down the start-up costs.

Test automation minimizes the necessity to perform manual and time-consuming tasks, giving testers more time to spotlight more pressing issues about the product.

Another way that test automation saves money has been parallel testing. Instead of manually running Johnson Controls AP VMA1420 0 at a time, one tester can run multiple tests without any additional effort on their part.

Test automation replaces manual testing
This is true in a few ways, but false in a few others. See, right now, some tests just can?t be automated. You can find just some things that cannot replace a human?s insight. The easiest way to look at automated testing is that it complements manual testing.

These are why hardly any software companies and development teams have fully automated testing systems in place. Most focus on a 50:50 manual to automated tests ratio.

Also, instead of inhibiting human interaction, some test automation platforms even allow collaboration.

Choosing a Test Automation Tool and Platform
You now know what automated testing is and what it isn?t. You also now have an over-all idea of which tests can be automated and otherwise. That's where we?re likely to introduce automation tools and platforms.

There is a wide selection of test automation tools and platforms available for development teams of different sizes. Choosing one may be the challenge. So how do you select a test automation tool or platform?

All you have to do is choose one which works with your project. Understanding assembling your project requirements is key to finding the perfect automation tool. One platform could be the highest-rated, but if a less-popular platform does just what you need to be done then this is the platform you use.

For example, a paid test automation tool might look good since it offers parallel testing. but does assembling your project need parallel testing? You might like to check out open-source testing tools if there is no allotted budget for testing tools in assembling your project.

You might also want to consider the general direction of the development team or the culture of the company you belong to. Aside from your current projects, think about your future projects too. Some automated tests may be used for testing different projects and, if you can successfully reuse your tests, then that provides you a head start for your next projects.


Conclusion
Some of the most common misconceptions about automation are:

Test automation provides testers and developers with an increase of ?free? time.
Test automation is very expensive.
Test automation is intended to get rid of every single manual test.
When looking for test automation tools and platforms, you should look at:

The project you?re working on so you can choose the features you need
The projects you may be working on later on to save lots of you time
The project?s budget
Testing automation is the process of automating repetitive, time-consuming, and objective manual tests. It can help development teams save time, money, and man-hours. Not all test automation tools are made equal though, and you also need to choose one which works best for the projects.
