It can automate both web and Windows applications.It could only automate web applications.

17. What are some of the Selenium substitutes?

Selenium has always been one of the most famous test automation technologies used by several organizations. It is, nevertheless, a highly technical tool with a big learning curve, and it may not be appropriate for all testing jobs. Several notable substitutes have arisen in recent times, which are listed here −

  • Cucumber - It’s an open-source testing tool that enables authoring tests in a straightforward, basic language understandable by everybody on the team. It emphasizes on behavior-driven development, in which the human-readable specification of the functionality is utilized as the foundation for testing.

  • Cypress - Cypress is an open and free testing tool. It’s developed in JavaScript and has become incredibly popular lately due of its accessibility and extensive capabilities that enable you to do browser testing.

    Cypress makes it simple to develop and debug unit tests, end-to-end tests, and integration tests. It also enables collecting photos and recordings to aid to replicate the issues.

  • Robot Framework - Robot Framework is a general open-source automation framework. It will be used for test automation and robotic process automation (RPA) (RPA).

18. What is the Robot framework? Provide a short summary of its structure.

Robot Framework is an extremely popular, open-source automated test framework used mostly for robotic process automation (RPA) (RPA). Robotic process automation seeks to imitate human activities and interactions using software. Compared to actual people, robotic automation can comprehend (to an extent) what is on display, push keys and buttons, browse to links and retrieve data.

The Robot Framework is developed in Python and operating system independent. Most of the libraries in the ecosystem are also open-source. It features a modular design available for expansion with other libraries. It describes the test data in files using a particular syntax that’s exclusive to the framework. A test suite has numerous such tests.

Once you begin the implementation of the tests, the Robot Framework decodes the test data and utilizes the key phrases given by the libraries to communicate with the program. These libraries connect with the program actively or passively through driver tools.

The Robot Framework conducts the test from the command line. But, you may access complete statistics and records in both XML and HTML formats. The framework includes decent support for standard libraries out-of-box, e.g. ArchiveLibrary, Browser Library, DataDriver Library, HttpRequestLibrary (for Java), etc.

19. What are the test library APIs supplied by the Robot Framework?

The Robot Framework offers three test library APIs.

  • Static API − A package or a class comprising procedures translates immediately to the keyword names that accept the same parameters as the implementing methods.

  • Dynamic API − The names of the keywords to apply as well as how to execute is decided at runtime.

  • Hybrid API − Integration of both the static and dynamic API. Libraries are classes holding the functions that inform them which keywords to execute, but those keywords must be directly accessible.

20. How would you automate the fundamental login in a web application?

Provided a tester has established the testing environment and a test tool like Selenium, below are the procedures I would follow to automate the login feature.

Verify the login personally to comprehend all the text boxes, checkboxes, and buttons on the login screen. Keep a track of the pages the user is forwarded to in both successful and failed logins.

Create a test dataset containing the username and password combos. The inputs comprise of varied lengths and feature alphanumeric character sets.

Generate test cases to examine alternative pathways the user could take in a real-world scenario. Simply record the anticipated outcomes for every test scenario.

In the test tool, setup each test case to be directly launched, and utilize the test data provided in step 2. Note the situations where the actual output doesn’t meet the intended outcome.

Check and confirm the success/error statements and the redirection after each login session.

21. What are the hazards connected with automated testing?

While test automation offers significant advantages such as efficient and reliable, repetitive tests, there are a few concerns a team should be mindful of.

Negative ROI

A group might make a big commitment to get automated testing underway. Automated testing demand loads of code and costly tools. Developers and testers invest substantial effort in studying and deploying automated tests.

Yet, once it’s put into reality, the team can learn that the testing technique is not offering any actual benefit, as the product is complicated with continuously changing configurations and functionalities. They have to maintain the exams regularly up-to-date.

Playing catch-up with the technology

Like any product, test automation tools and frameworks go through ongoing growth. There is a strong learning path to the automation tools and really need sufficient programming skills.

Rather than choosing a tool and utilizing it properly, the development/testing team wastes their time studying and experimenting with other tools and technologies. In that instance, the automated testing might not fulfill its initial claimed benefit.

Operational Concern

All programming has to be managed and maintained up-to-date with the increasing demands and addressing errors. Test automation code is no exception to it.

Rather than making improvements and addressing issues in the program, if developers and testers find themselves investing most of their time working on the automation framework, automated testing has flopped.
