Estuate Software Interview Questions, Process, and Tips

Sanity testing is a narrow and deep testing approach while smoke testing is a wide and shallow testing approach.

• Sanity testing is done to check if the critical functionalities of the application are working fine after a small change is made.

• Smoke testing is done to check if the application is stable enough to proceed with further testing.

• Sanity testing is a subset of regression testing while smoke testing is a subset o...read more

Framework execution flow involves the sequence of steps followed by the automation framework to execute a test case.

• The framework reads the test case from the test data source.

• It then identifies the test steps and their corresponding actions.

• The framework then executes the test steps in the defined sequence.

• During execution, the framework captures and reports the test results.

• Finally, the framework generates a test rep

TestNg is a testing framework used to run failed test cases and manage test suites.

• TestNg allows rerunning of failed test cases using the 'rerun-failed.xml' file.

• It provides annotations to manage test execution flow and grouping of test cases.

• TestNg generates detailed test reports and supports parallel test execution.

• It also provides data-driven testing and integration with other tools like Selenium and JUnit.

Jenkins jobs can be scheduled using the Build Triggers option. The flow includes SCM polling, build, and post-build actions.

• Go to the job configuration page and select Build Triggers

• Choose the appropriate trigger option such as Poll SCM or Build periodically

• Configure the trigger settings such as the schedule or polling interval

• Add build steps and post-build actions as required

• Save the job configuration

• Jenkins will auto...read more

Object-oriented programming concepts that help in building modular and reusable software.

• Encapsulation - bundling data and methods that operate on that data within a single unit

• Inheritance - creating new classes from existing ones, inheriting their properties and methods

• Polymorphism - ability of objects to take on many forms, allowing different objects to be treated as if they were the same type

• Abstraction - hiding imp...read more

Program to find second highest number in an array of strings.

• Convert strings to integers

• Sort the array in descending order

• Return the second element

Query to find salary more than 10000 and dept belongs to finance

• Use SELECT statement with WHERE clause

• Specify salary greater than 10000 and department as finance

• Use AND operator to combine conditions

A program to find the occurrence of characters in a given string.

• Create an empty dictionary to store the character count.

• Loop through each character in the string.

• If the character is already in the dictionary, increment its count.

• If the character is not in the dictionary, add it with a count of 1.

• Return the dictionary with character counts.

Verification ensures that the software meets the specified requirements, while validation ensures that the software meets the customer's needs.

• Verification checks if the software is built according to the design specifications.

• Validation checks if the software meets the customer's requirements.

• Verification is done before validation.

• Verification includes reviews, walkthroughs, and inspections.

• Validation includes testing

100% test coverage is not possible, but we can aim for maximum coverage by prioritizing tests and using automation.

• Prioritize tests based on risk and criticality

• Use automation to cover repetitive and time-consuming tests

• Perform code reviews to ensure all code paths are covered

• Continuously monitor and update test suite

• Collaborate with developers to ensure all changes are tested

• Use tools like code coverage analysis to id
