Wipro Interview Questions, Process, and Tips

Manual testing is the process of manually testing software for defects without the use of automation tools.

• Manual testing involves testers executing test cases manually to identify bugs and issues in the software.

• Testers follow predefined test cases and scenarios to ensure the software meets the specified requirements.

• It is a time-consuming process but allows for human intuition and creativity in testing.

• Examples of ma...read more

Automation testing is the process of using tools and scripts to execute test cases and compare actual outcomes with expected outcomes.

• Automation testing helps in reducing manual effort and time required for testing

• It increases test coverage and efficiency

• Examples of automation testing tools include Selenium, Appium, and JUnit

Software development life cycle (SDLC) is a process used by software development teams to design, develop, test, and deploy software.

• SDLC consists of several phases such as planning, analysis, design, implementation, testing, and maintenance.

• Each phase has its own set of activities and deliverables to ensure the software meets the requirements.

• Examples of SDLC models include Waterfall, Agile, and DevOps.

• SDLC helps in e...read more

Software testing life cycle is a process of planning, designing, executing, and reporting on tests throughout the software development life cycle.

• It involves planning the testing activities

• Designing test cases based on requirements

• Executing the test cases to identify defects

• Reporting and tracking defects

• Retesting and regression testing

A defect in manual testing refers to an issue or flaw in the software application that is identified during the testing process.

• Defects can include functionality issues, design flaws, performance problems, or security vulnerabilities.

• Defects are typically logged in a defect tracking system and assigned to developers for resolution.

• Examples of defects include a button not working as intended, incorrect calculations in a...read more

You can use a temporary table to change datatype without altering the original table.

• Create a new temporary table with the desired datatype

• Insert data from the original table into the temporary table

• Drop the original table

• Rename the temporary table to the original table name

Inner join returns only the matching rows between two tables, while left join returns all rows from the left table and the matching rows from the right table.

• Inner join result: 1 2 3

• Left join result: 1 2 3, 4 5 6, 7 8 9

Some tools used for ETL testing include Informatica PowerCenter, Talend, IBM InfoSphere DataStage, and Apache Nifi.

• Informatica PowerCenter

• Talend

• IBM InfoSphere DataStage

• Apache Nifi

Types of waits in Selenium include implicit, explicit, and fluent waits.

• Implicit wait: Waits for a certain amount of time before throwing a NoSuchElementException.

• Explicit wait: Waits for a certain condition to occur before proceeding further in the code.

• Fluent wait: Waits for a condition to be true with a defined polling frequency.

• Example: driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Fibonacci program in Java generates the Fibonacci sequence up to a specified number.

• Use a loop to generate the Fibonacci sequence

• Start with 0 and 1 as the first two numbers in the sequence

• Each subsequent number is the sum of the two preceding numbers

• Example: 0, 1, 1, 2, 3, 5, 8, 13, ...
