10+ Lead Quality Engineer Interview Questions and Answers

Extent report can be implemented by adding the extent report dependency, creating an instance of ExtentReports class, and using ExtentTest class to create test logs.

• Add the extent report dependency in the project's pom.xml file

• Create an instance of ExtentReports class in the @BeforeSuite method

• Create an instance of ExtentTest class in the @BeforeMethod method

• Use ExtentTest class to log test steps and results

• Generate the report using the flush() method in the @AfterSuite metho...read more

Testing methodologies, defect life-cycle, high priority vs low severity defects, and Agile.

• Testing methodologies include black box, white box, and grey box testing.

• Defect life-cycle includes identification, logging, prioritization, fixing, retesting, and closure.

• High priority and low severity defect example: spelling mistake in a critical message.

• Low priority and high severity defect example: cosmetic issue in a non-critical area.

• Agile is an iterative and incremental approach...read more

Quality tools and systematic approach for problem solving

• Quality tools include Pareto analysis, fishbone diagram, control charts, etc.

• Systematic approach involves defining the problem, analyzing root causes, developing solutions, implementing changes, and monitoring results

• Examples: Using a fishbone diagram to identify potential causes of defects in a manufacturing process, then using control charts to monitor the process over time

JDK is a development kit, JRE is a runtime environment, and JVM is the virtual machine for executing Java bytecode.

• JDK (Java Development Kit) includes tools for developing Java applications, such as compilers and debuggers.

• JRE (Java Runtime Environment) provides the libraries and components necessary to run Java applications but does not include development tools.

• JVM (Java Virtual Machine) is the engine that executes Java bytecode, converting it into machine code for the host...read more

Method overloading allows multiple methods with the same name but different parameters; overriding replaces a method in a subclass.

• Method Overloading: Same method name, different parameter types or counts. Example: 'add(int a, int b)' and 'add(double a, double b)'.

• Method Overriding: Redefining a method in a subclass that already exists in the parent class. Example: 'void display()' in both parent and child.

• Overloading is resolved at compile time (static polymorphism), while o...read more

Automation execution can encounter various exceptions, impacting test reliability and results.

• Timeout Exceptions: Occur when a test waits too long for an element to appear, e.g., waiting for a button that never loads.

• Element Not Found: Happens when the automation script cannot locate a UI element, e.g., a missing input field on a form.

• Stale Element Reference: Occurs when a web element is no longer attached to the DOM, e.g., after a page refresh.

• Assertion Failures: Triggered w...read more

Code for database connectivity

• Import the required database driver

• Create a connection object using the driver

• Establish connection to the database using connection object

• Execute SQL queries using the connection object

• Close the connection

SPC stands for Statistical Process Control and MSA stands for Measurement System Analysis.

• SPC is a method of quality control which uses statistical methods to monitor and control a process.

• MSA is a method used to assess the variation in measurement processes.

• SPC helps in identifying and reducing variation in a process, while MSA helps in ensuring that measurement systems are accurate and reliable.

• Examples of SPC tools include control charts and histograms, while examples of M...read more

8D steps for problem solving with real example

• D1: Establish the team - Form a cross-functional team including stakeholders

• D2: Define the problem - Clearly define the problem statement and its impact

• D3: Develop interim containment actions - Implement temporary solutions to prevent further issues

• D4: Identify root cause - Use tools like Fishbone diagram or 5 Whys to determine the root cause

• D5: Develop permanent corrective actions - Implement long-term solutions to prevent recurr...read more

Reversing a string in Java can be achieved using various methods, including loops, recursion, and built-in functions.

• Using StringBuilder: StringBuilder sb = new StringBuilder('Hello'); sb.reverse(); String reversed = sb.toString();

• Using a loop: char[] charArray = 'Hello'.toCharArray(); for (int i = charArray.length - 1; i >= 0; i--) { System.out.print(charArray[i]); }

• Using recursion: public static String reverse(String str) { if (str.isEmpty()) return str; return reverse(str....read more

The question is asking for a Java program that calculates the sum of two numbers.

• Create two variables to store the numbers to be added.

• Use the + operator to add the two numbers together.

• Print or return the result of the addition.
