Appium test automation framework has support for cross-platform. This framework allows the developers to design and write tests for applications on multiple platforms. Appium is based in Node.js and used for windows desktop application. It has beta support for test automation of Mac OS desktop applications. Appium is based on the tenets which are related to recompiling the app for automation and locking to a specific language or framework.
Web testing automation tools are built using multiple languages and provide support for different language to develop tests. Developers and Testers develop automated tests. Testers design scenarios and developers code the tests. The automation tools can be based on multiple approaches like data driven or keyword driven.
Selenium is a popular test automation tool for web applications. This framework has support for writing the tests in Java, Groovy, Python, C#, PHP, Ruby and Perl. Selenium has support for browsers such as Chrome, Firefox, IE and Headless browsers. To use this test automation framework, developers who have advanced programming skills are needed.
2.2.2 Katalon Studio
Katalon Studio has features related to test automation of API/Web services, and Web applications. This studio has support for both SOAP and RESTful API. Cucumber is used to design test scenarios in natural languages. The test automation can be augmented with other capabilities such as in depth views, reporting and analytics.
Serenity opensource framework is used to develop automated web test cases. It is used to design and develop tests which are maintained for long term. Serenity has features related to reporting, test coverage and project progress.
Citrus opensource test automation tool supports web application testing and testing with other messaging protocols. You can use Citrus for REST, JMS and SOAP messaging protocols. Citrus can be integrated with Selenium. It supports testing the messaging protocols such as REST, SOAP and JMS.
Citrus will identify whether the program is appropriately dispatching communications and whether the results are as expected. It can also be integrated with Selenium if another front-end functionality testing has to be automated. Thus, this is a specific tool that is designed to automate and repeat tests that will validate exchanged messages.
2.3.1 Apache JMeter
Apache JMeter performance testing automation tool is used for testing applications which are static and dynamic. It is used to design and develop performance load tests for applications deployed on a server or a distributed network of servers. It has features related to Test plan recording, reporting and parallel sampling of programs executed by multiple thread groups.
Gatling is a test automation framework for load and performance testing. You can design and develop tests for long term and maintain them. Gatling is protocol agnostic. Gatling is architected using asynchronous architectural pattern. It can be used for simulating more than 1000 concurrent virtual users.
Locust load testing tool is used for distributed and user load testing. You can use Locust for load-testing the web sites. Locust can be used for simulating virtual concurrent users and identifying the maximum number of concurrent users a system can handle. It can be used to identify the issues in the code related to scalability and performance.
Locust’s architecture is event-based, and it uses gevent to support light-weight process. You can design and develop test cases in PythonLocust to support distributed server load testing.
Tsung load testing tool is a opensource framework used for loadtesting distributed applications. It provides support for messaging server testing based on protocols such as WebDAV, SOAP, PostgreSQL, MySQL, LDAP, MQTT, and Jabber/XMPP .
Siege opensource framework is used for load testing web applications. It is used for benchmarking applications for performance and scalability. Siege has support for messaging protocols such as REST, HTTPS and FTP protocols. It is used for simulating concurrent virtual users accessing the web application. Siege had support initially for GNU/Linux and later was supported for AIX, BSD, HP-UX and Solaris.
Httperf load testing framework is an opensource tool for load testing the web based applications. The reports are generated related to web server performance and http payload.
Taurus is an opensource load test automation framework. It is developed over JMeter and other tools such as Grinder, Gatling and Selenium. Taurus has features to design and develop test cases for load testing. It has DSL based test scripting framework to design test scenarios. Taurus has support for maintaining test scripts and DSL driven tests. It has features such as real time reporting, exporting test results into multiple fomats and integration with BlazeMeter.
Goad load testing tool is used for load testing distributed applications. It is based on AWS Lambda. GOAD provides support for handling web loads from different AWS Geographic regions. It is used for simulating 10000 concurrent requests.
2.3.9 Apache Bench
Apache Bench is an open source load testing tool used for benchmarking the applications for load and scalability. It provides the reports for apache server performance. Apache Bench has support for concurrent virtual users simulation.
There is a surge in the usage of test automation tools in software engineering across the IT industry in the world. These tools are used for testing automation of functional testing and load testing of desktop and web applications. Large size projects need test automation as the regression tests need to be run for validating the builds and releases.
“Shift Left” approach is taken for testing in two to three weeks sprints in agile iterations. The shift left in a typical agile iteration is related to the early focus on testing. This initiative develops the rigor in the process for testing automation and accountability for testing. The test designers focus on creating test automation frameworks for functional and performance testing.
For desktop test automation, Winium is the popular tool for windows applications testing automation and Appium is for MacOS application testing automation. Selenium is the most popular tool for web application test automation. Katalon Studio is useful for novice programmers and testers. Apache JMeter is the best performance load testing tool.
