Need How To tips, phrases, and words for answering job interview questions.

Question 1:

What is Selenium?

Answer:

Selenium is a robust test automation suite that is used for automating web based applications. It supports multiple browsers, programming languages and platforms.

Question 2:

What are different components of selenium?

Answer:

Selenium has four components

1. Selenium WebDriver - Selenium WebDriver is used to automate web applications using browser's native methods.
2. Selenium IDE - A firefox plugin that works on record and play back principle.
3. Selenium RC - Selenium Remote Control (RC) is officially deprecated by selenium and it used to work on javascript to automate the web applications.
4. Selenium Grid - Allows selenium tests to run in parallel across multiple machines.

Question 3:

What are some advantages of selenium?

Answer:

Following are the advantages of selenium

1. Selenium is open source and free to use without any licensing cost.
2. It supports multiple languages like Java, ruby, python etc.
3. It supports multi browser testing.
4. It has good amount of resources and helping community over the internet.
5. Using selenium IDE component, non-programmers can also write automation scripts
6. Using selenium grid component, distributed testing can be carried out on remote machines possible.

Question 4:

What are some limitations of selenium?

Answer:

Following are the limitations of selenium

1. We cannot test desktop application using selenium.
2. We cannot test flash based apps using selenium.
3. For creating robust scripts in selenium webdriver, programming langauge knowledge is required.
4. We have to rely on external libraries and tools forperforming tasks like - logging(log4J), testing framework-(testNG, JUnit), reading from external files(POI for excels) etc.

Question 5:

Why do you prefer Selenium Automation Tool?

Answer:

• Free and open source
• Have large user base and helping communities
• Cross browser compatibility
• Platform compatibility
• Multiple programming languages support

Question 6:

What is Automation Testing?

Answer:

Automation testing is the process of testing the software using an automation tools to find the defects. In this process, executing the test scripts and generating the results are performed automatically by automation tools. Some most popular tools to do automation testing are HP QTP/UFT, Selenium WebDriver, etc.

Q uestion 7:

What are the benefits of Automation Testing?

Answer:

• Saves time and money. Automation testing is faster in execution.
• Reusability of code. Create one time and execute multiple times with less or no maintenance.
• Easy reporting. It generates automatic reports after test execution.
• Easy for compatibility testing. It enables parallel execution in combination of different OS and browser environments.
• Low cost maintenance. It is cheaper compared to manual testing in a long run.
• Automated testing is more reliable.
• Automated testing is more powerful and versatile.
• It is mostly used for regression testing. Supports execution of repeated test cases.
• Minimal manual intervention. Test scripts can be run unattended.
• Maximum coverage. It helps to increase the test coverage.

Question 8:

What type of tests you have automated?

Answer:

Our main focus is to automate test cases to do Regression testing, Smoke testing, and Sanity testing. Sometimes based on the project and the test time estimation, we do focus on End to End testing.

Question 9:

How many test cases you have automated per day?

Answer:

It depends on Test case scenario complexity and length. I did automate 2-5 test scenarios per day when the complexity is limited. Sometimes just 1 or fewer test scenarios in a day when the complexity is high.

Q uestion 10:

Compare Automated Testing & Manual Testing

Answer:

Question 11:

Which all browsers are supported by selenium webdriver?

Answer:

Some commonly used browsers supported by selenium are
