TestNG profiling is a feature that allows developers to analyze the performance of their test cases and identify bottlenecks.

• TestNG profiling helps in identifying slow-running test cases and optimizing them for better performance.

• It provides detailed information on the execution time of each test method, helping developers prioritize optimization efforts.

• Profiling can be done at the method level, class level, or suite ...read more

CSS selector is used to select HTML elements based on their id, class, attributes, etc. XPath is a language for navigating XML documents.

String is immutable in Java to ensure security, thread safety, and optimization.

• String objects are stored in the String pool, which helps in memory optimization.

• Immutable strings are thread-safe, as their values cannot be changed once created.

• String immutability prevents malicious code from modifying sensitive data.

• Example: String str = "Hello"; str.concat(" World"); // This does not change the original string value.

Use Selenium Java code to identify broken links on a web page

• Create a WebDriver instance using Selenium

• Find all the links on the web page using findElements method

• Iterate through each link and check for response code using HttpURLConnection class

• Identify links with response code other than 200 as broken links

Code for Explicit wait in Selenium WebDriver

• Import WebDriverWait and ExpectedConditions classes

• Specify the maximum time to wait and the polling interval

• Use ExpectedConditions methods like elementToBeClickable, visibilityOfElementLocated, etc.

• Apply the wait to a specific element or condition

To automate a drop down, you can use tools like Selenium WebDriver to interact with the drop down element and select options programmatically.

• Use Selenium WebDriver to locate the drop down element on the webpage

• Identify the options within the drop down using findElements method

• Use select class in Selenium to interact with the drop down and select desired option

String memories are allocated in different places depending on the programming language and platform.

• In C, string memories are allocated on the stack or heap depending on how they are declared.

• In Java, string memories are allocated on the heap.

• In Python, string memories are allocated on the heap and are managed by the interpreter.

• In JavaScript, string memories are allocated on the heap and are managed by the garbage co

The == operator compares the reference of two String objects, while the equals() method compares their values.

• The == operator checks if two String objects refer to the same memory location.

• The equals() method checks if two String objects have the same sequence of characters.

• Using == for String comparison can lead to unexpected results.

• Example: String str1 = "hello"; String str2 = "hello"; str1 == str2 will return true ...read more

Code for setters and getters methods

• For each instance variable, create a setter and getter method

• Setters should take in a parameter and assign it to the instance variable

• Getters should return the value of the instance variable

• Naming convention for setters and getters should follow camelCase

TestNG allows test case execution order to be specified using priority attribute or by using dependsOnMethods attribute.

• TestNG executes test cases in the order specified by priority attribute.

• If priority attribute is not specified, TestNG executes test cases in alphabetical order of method names.

• TestNG also allows test case execution order to be specified using dependsOnMethods attribute.

• dependsOnMethods attribute spec...read more
