Salesforce QA Engineer Coding Questions

Salesforce aims to reduce the feedback loop time for its CI/CD pipeline by running tests in parallel across multiple agents. Your task is to design a function to manage the parallel execution of test cases.
- def run_tests_in_parallel(tests: List[str]) -> List[Result]: takes a list of test names and runs them concurrently, returning their results.Example 1:
Input: tests = ['test_login', 'test_checkout', 'test_dashboard']
Output: [Result(success=True), Result(success=False), Result(success=True)]
Explanation: Runs the listed tests in parallel and returns their execution results.Constraints:
- tests will contain between 1 and 100 test names, each string not exceeding 30 characters.

Salesforce relies on maintaining a highly reusable and scalable test automation framework for its web applications. Utilizing the Page Object Model (POM) can enhance maintainability and readability of tests.
You are tasked with creating a framework where each page of the application is represented by a separate class. Each class contains methods that interact with the elements of that specific page.
- class LoginPage: represents the login page.
- def enter_username(username: str) -> None:: inputs the username into the provided field.
- def enter_password(password: str) -> None:: inputs the password into the provided field.
- def click_login() -> None:: submits the login form.Example 1:
Input: username = 'admin', password = 'password123'
Output: None
Explanation: The methods should invoke actions to fill the username and password fields, then click the login button.Constraints:
- username and password should be strings limited to 20 characters each.
- The methods should not return any value after their execution.
