What is Automated testing?

Automated testing is a software testing methodology that streamlines the process of verifying software functionality and compliance with requirements prior to commercial release. An organisation may conduct targeted software tests more quickly and without the need for human testers by using automated testing. Large or recurring test cases are the ideal candidates for automated testing.

Testing tools run predefined sequences as part of automated software testing. Software is tested, findings are reported, and results are compared with previous test runs using automated testing tools. You may develop an automated test script once and use it again and again.
Unit, programming interfaces (API), and regression testing are just a few of the many scenarios in which an organisation might use automated testing. The primary advantage of automated testing of software is in the reduction of manual labour into a collection of scripts. For instance, a group working on quality assurance (QA) should consider automating unit testing if it takes up a significant portion of their resources.

Software development processes that involve continuous testing, continuous integration (CI), and continuous delivery (CD) greatly benefit from the use of automated tests, which can be carried out frequently and at any time of day.

Why Automated Testing is required?

You might not be aware that new bugs that weren’t in prior versions of the programme could exist when fresh releases or bug patches are made. Checking the software as a whole is the best method to find out. There are undoubtedly many disadvantages to manual testing that may be addressed by automation. The following justifies the need for automated testing:

Automation testing allows for the absence of human interaction and allows for unattended test runs.
Testing multilingual websites by hand may be quite challenging.
Automation helps to boost test execution pace.
Errors won’t occur during automation testing.
Test coverage is increased in part by automation.

How it works?

The phases in the automated testing process often go like this:

Choose a tool for testing. This is contingent upon the kind of the testing being conducted and if the tool in question is compatible with the platform that the programme is being created for.
Describe the automation’s reach. This indicates the degree of automation used in software testing.
Arrange, create, and advance. Creating test scripts and organising the automation approach are part of this stage.
Carry out the examination. Automation scripts are used for software testing. Additionally, the testing tool need to gather information and offer thorough test findings.
upkeep. Automated test scripts are updated and changed in response to new software builds as needed.

Appium- Appium is a freely available and open source framework for evaluating user interfaces in mobile applications. Appium supports web, native, and hybrid application testing. Simulators, emulators, and actual devices can all be used for automation testing.

Calabash- Tests for iOS and Android apps may be created and run using the open-source Calabash testing framework. Tests developed in Cucumber and Ruby are supported by this Automated User Interface framework.

Similarities and Differences between Calabash and Appium

Mobile app testing is done using Appium and Calabash. While there are other web app testing tools available, these are the ones made especially for testing mobile apps. Both have a thriving and active community and are available as open source. This leads to frequent addition of new features and prompt issue fixes for both. Additionally, both of them are capable of testing any kind of mobile application created in any language.
The primary distinction is that Appium does automated testing, whereas Calabash conducts acceptance testing. Whereas Appium test cases may be created in a number of languages, including Java, JavaScript, and Python, Calabash test cases are written in English sentences using a language called Gherkin.

Appium vs Selenium vs Calabash:

When it comes to choosing between Appium, Selenium, and Calabash, there are several factors to consider. Here are some of the key differences between these three test automation frameworks:

Platform Support: Appium and Calabash support both Android and iOS platforms, while Selenium only supports web applications.

Language Support:Selenium supports the following programming languages: Java, Python, Ruby, and C#. Appium supports several of the same languages as Selenium does, along with PHP and JavaScript. It is necessary to be familiar with Ruby or another language that supports the Cucumber syntax in order to use Calabash.

Installation and Setup:Appium and Selenium may both be installed and configured without too much difficulty, although Calabash requires the installation of Ruby and its dependencies.

Test Creation:Appium and Selenium give developers a lot of options when it comes to developing tests by allowing them to utilise any testing framework of their choosing. Contrarily, Calabash makes use of the Cucumber syntax and demands an understanding of either Ruby or another language that does as well.

Test Execution:Appium and Calabash allow test execution on actual devices, whereas Selenium requires the usage of browser drivers. Yet, because Selenium provides cross-browser testing, it is a great choice for web applications.

Community support:Each of the three test automation frameworks has an active online community that contributes to tool development and support. However, because Selenium has the largest community, it also has the most resources and documentation.

Framework Support:Selenium, one of the first and most popular automated testing frameworks, has a large developer community that is constantly working to improve and add new features. In contrast, the communities for Appium and Calabash are a little bit smaller, so it is conceivable that you won’t discover as many ready-made solutions as you would for Selenium.

Testing Environment:Selenium is made for web applications, but Appium is made exclusively for testing mobile apps. Contrarily, Calabash can be used to test both web and mobile applications. Appium and Calabash are better options if testing for mobile applications is your primary priority. Selenium is the finest alternative if you want to test web applications.

Language Support:Selenium only supports a small number of programming languages, such as Java, Python, C#, and Ruby, in contrast to Appium, which supports Java, Python, Ruby, PHP, JavaScript, and C#. The only languages that Calabash supports are Ruby and Cucumber. Selecting a tool that is compatible with the programming language you are most accustomed to is essential.

Ease of Use:Selenium is a good option for beginners because it is relatively straightforward to use and has an easy-to-understand interface. Contrarily, the learning curve for Appium and Calabash is higher, and it could take some time to get acquainted to their user interfaces.

Performance:Selenium is well known for its great performance and is frequently used by businesses with extensive needs for test automation. Although Calabash and Appium have comparable performance metrics, there may be limitations when running several tests at once.
