What is testing and what is test automation

Automation Testing

At some point, manual testing proved to be time-consuming, sometimes bug-missing, and just not enough. Manual testing can never be substituted with automated only, but automation testing appeared as its strong assistant offering unquestionable benefits for the team:

 

Increased test coverage

With test automation practice we will run many tests during a short time. With more test cases done, especially at large-scale projects, there’s more confidence the system will work properly. However, with a high percentage of automated tests run, it doesn’t always mean the standard of the appliance will jump directly. It all depends on testing things that matter and on the standard of tests also, not just the amount of things tested.

 

Saved time, saved money

Automated tests can reduce tons of your time spent on running repetitive tests. What 2 manual QA engineers manage to try to do in 3 days, 1 automation engineer manages to try to do in 1 day. New features are often tested in an automatic way, but it depends on how the team decides on their testing workflow. However, the important choice lies in defining the framework and style for writing scripts which will allow testing the appliance with ease.

 

Automation helps detect unexpected breaks within the systems

Human error causes trouble for manual testing. As soon as new functionality is launched at large projects, changes can cause bugs in parts of the answer already developed and tested. Manual testers would spend eternity detecting those bugs whenever new functionality goes to the assembly stage. That’s why it’s much easier to rent automation testers and make certain the system works coherently.

 

When and why automation testing doesn’t help? or just doesn’t catch defects?

Automation testing is very praised, as everything goes alongside “automation” within the definition. Of course, automation processes are powerful, that’s what the teams strive for – the pc is doing everything for you at an expected high-quality level you’ll believe. However, there are dark sides to automation and therefore the reasons why in some cases automation won’t work for your team.

 

Automation testing is believed to figure perfectly for regression testing, but even here some regression test bugs can slip into production. Reason #1 is often poorly designed automated test scenarios.

Then, QA engineers’ coding skills matter also since having test scenarios ahead of them they need to script most efficiently to not miss a bug. If poorly designed test scenarios meet engineers with poor testing knowledge, then expect nothing but a couple of bugs slipping freely into production.

 

Another reason is that the application environment. Executions of automated tests are often halted due to issues with the browser where the app can run, 3rd party integrations, dependencies, and so on. Measures should be taken into consideration to not waste time with automation tests that won’t show correct results.

 

And the last, poor analysis of filed automated tests can cause ineffective usage of automated tests. Reporting which is completed manually should be analyzed inside bent understand reasons for failures and whether or not they aren’t hidden by another issue.

 

Basics of Automation testing

Tests that will not be performed manually, as an example, API, Performance, Security testing, and therefore the whole back-end testing generally, are going to be conducted only with the assistance of special automation testing software. In practice, they’re automated tons and are well worth the efforts for the advantage of reduced time.

 

Desktop application testing

Desktop apps are installed by a user on a selected OS

Desktop application testing checks the functionality, security, usability, and stability of the appliance

While testing a desktop application, it’s important to check:

 

  • Graphical interface
  • Functionality
  • Performance & Load
  • Security
  • Compatibility

Web application testing

Web testing differs from the desktop application because it uses a browser  – the client-side to request an internet page (the server-side). Communication between the client and therefore the server-side goes via HTTP/HTTPS, so QA engineers should have an honest understanding of this to be ready to assess how the online application works.

 

Performance testing, Security testing, Cross-browser, and Responsiveness testing are critical in terms of Web Testing but aren’t such a necessity for desktop testing. The rationale is sites run constantly during a browser and cargo tons of content at high speed to satisfy the requests of an endless number of users.

Working smoothly in performance, security, and integration aspects is extremely important for an internet site to be promoted among the end-users. Otherwise, competitors will cash in.

 

Web sites are built using web services. Web services are often tested in isolation which suggests no involvement of web browsers and direct communication with web servers. Such an isolated approach makes testing much faster, easier, and offers more control as QA engineers can control and use data of various error scenarios.

 

Cross-browser web testing

Imagine building an application that ought to run on Google, Mozilla, and Opera browsers, but it seems that some browsers don’t support some functional parts of an application or its remake,

To avoid this at release, QA engineers need to conduct cross-browser web testing. Though cross-browser issues are rare and mostly connected with the quaint versions of the browser, this sort of testing is often automated and chosen just for the foremost important scenarios on different browsers.

 

Mobile application testing

Web responsive applications allowed users to access the apps not only through their desktop browser but through their smartphones which altered the methods of testing also,

 

Native applications are installed on a mobile device and are designed specifically for a particular platform, let’s say either iOS or Android. Classic samples of native apps are often photo editor you download from Google Play or the App Store. while web responsive applications are sites accessed via the browser but offer a view adjusted for mobile users.

Progressive web applications also are accessible via the browser on your mobile device or laptop but are often added to your home screen on your smartphone and used offline. An example of PWA are often Pinterest.

 

Hybrid applications are very almost like native apps but are often accessed via WebView within the browser. The bulk of hybrid apps are cross-platform.

An example of a hybrid app is often Facebook, Instagram, or Uber.

 

Testing mobile applications are often done via emulator software which showcases what happens with the appliance when the automation tests are running and scanning necessary parts of the appliance. Automated tests for mobile devices can reduce tons of your time for the team. they will be pushed for a particular deadline and supply the testers with automatic results, which depict at what place the bug is found.

API testing

In contrast to functional testing when the tester interacts with the interface, in API testing there are not any activities for testing the visual, or front-end side, of the appliance. API testing is about testing the back-end of the appliance if to be precise – HTTP requests and responses from the server.

 

Why is API testing important? Imagine testing the sign-in sort of the appliance. You insert login, password, click the button and watch the items work only from the visual part. However, to check the appliance fully, we’d like to ascertain what’s happening behind the scenes. API testing starts with:

 

Knowing the URL address of the endpoint to which post request is shipped

Knowing the format: JSON, form-data, Multipart

Knowing what response status should be consistent with a response body

Analyzing the response and what it can say about the “health of the request”

API testing is widely practiced via Postman. Testers who are engaged in API checking should clearly understand what necessary libraries there are for API testing, how HTTP requests work, what their structure and methods are, understand endpoints and be ready to create collections and templates.

 

Conclusion                                                                                               

Performance testing may be a non-functional testing method performed as automation testing of a system’s performance at a particular number of business users on the online page, desktop, or mobile application. It’s useful for any application because not only functionality is vital but the performance, by the way, is often impacted intentionally or some functional features. It’s always beneficial for the project quality to check performance beforehand not postponing to the discharge and getting it.
