Best practices when using Playwright<\/h2>\n
Playwright is a powerful browser automation tool, here are some recommendations for using it effectively:<\/p>\n
1. Proper browser management<\/h3>\n
When automating browsers, it is important to manage the browser lifecycle effectively. It is recommended to create and close browser instances only when necessary. This helps to save memory and make tests run faster. If necessary, you can create and share browser instances between different tests or at the beginning and end of each test.<\/p>\n
2. Optimization of waiting for loading<\/h3>\n
Optimizing the wait for a page to load or for certain events is important to avoid unreliable and unstable tests. Using proper wait methods, such as waitForLoadState or waitForSelector, helps ensure that your tests are run in the correct context.<\/p>\n
3. Proper treatment of bugs<\/h3>\n
When automating browsers, it is important to treat bugs and unexpected situations correctly. Playwright provides methods to handle bugs such as catching exceptions with try-catch blocks, handling timeouts, or examining failed asynchronous operations.<\/p>\n

Best practices when using Playwright<\/h2>\n
Playwright is a powerful browser automation tool, here are some recommendations for using it effectively:<\/p>\n
1. Proper browser management<\/h3>\n
When automating browsers, it is important to manage the browser lifecycle effectively. It is recommended to create and close browser instances only when necessary. This helps to save memory and make tests run faster. If necessary, you can create and share browser instances between different tests or at the beginning and end of each test.<\/p>\n
2. Optimization of waiting for loading<\/h3>\n
Optimizing the wait for a page to load or for certain events is important to avoid unreliable and unstable tests. Using proper wait methods, such as waitForLoadState or waitForSelector, helps ensure that your tests are run in the correct context.<\/p>\n
3. Proper treatment of bugs<\/h3>\n
When automating browsers, it is important to treat bugs and unexpected situations correctly. Playwright provides methods to handle bugs such as catching exceptions with try-catch blocks, handling timeouts, or examining failed asynchronous operations.<\/p>\n
4. Parameterization of tests<\/h3>\n
Test parameterization allows you to run the same test scenario with different inputs or settings. Playwright allows easy parameterization of tests using a switch or configuration file. This practice helps to increase test coverage and ensure that you are testing different scenarios and different combinations of inputs.<\/p>\n
5. Use of assertions<\/h3>\n
It is important to use assertions to verify that your code is working properly and to ensure that your tests are correct. Playwright provides built-in methods to verify the state of a page or the existence of certain elements. The use of these methods, such as expect, helps in creating reliable and concise tests.<\/p>\n
6. Sustainability and reusability<\/h3>\n
When writing tests in Playwright, it is important to pay attention to maintainability and reusability of the code. It is recommended to create clear and well-documented tests that are easy to understand and modify. It’s also a good idea to create functions and classes for reusable parts of the code, which helps reduce duplication and makes tests easier to maintain.<\/p>\n
7. Proper logging and tracking<\/h3>\n
When writing and running tests, proper logging and tracking of events is important. Playwright provides options for recording events and logging different parts of the test. This logging helps to track and analyze the progress of tests, gather information about bugs and identify problem areas in the application.<\/p>\n
