  Scenario: You click a link or button that opens a new tab, and you want to switch to that tab and perform actions.   const [newPage] = await Promise.all([     context.waitForEvent('page'),         // Waits for a new tab to be opened     page.click('a[target="_blank"]'),     // Simulates clicking the link that opens a new tab   ]);   // Wait for the new tab to load   await newPage.waitForLoadState();   // Do something in the new tab   console.log('New tab title:', await newPage.title());   // Example: take screenshot of the new tab   await newPage.screenshot({ path: 'new-tab.png' });   await browser.close(); })(); Key Concepts: context.waitForEvent('page') : Waits for a new tab or popup. The Promise.all() ensures that the event and click happen together. newPage.waitForLoadState() : Ensures the new tab is fully loaded before interaction.

  The major XPath axes follow family tree terminology: self::  is you. Downward: child::  are your immediate children. descendant::  are your children, and their children, recursively. descendant-or-self::  (aka  // ): are you and your descendants. Upward: parent::  is your mother  or  father. ancestor::  are your parent, and your parent's parent, recursively. ancestor-or-self::  are you and your ancestors. Sideways (consider elements earlier in the document to be younger): previous-sibling::  are your younger siblings, in age order. following-sibling::  are your older siblings, in age order. previous::  are your younger siblings and their descendants, in age order. following::  are your older siblings and their descendants, in age order. --------------------------------------------------------------------------------------------------------------------- child::  will select the immediate descendants of the ...

  Again, you should rely on other methods since the regular expressions here will only validate the format. Make use of the   Luhn algorithm  to properly validate a card. VISA: ^4[0-9]{12}(?:[0-9]{3})?$ MasterCard: ^5[1-5][0-9]{14}$ American Express: ^3[47][0-9]{13}$ Diners Club: ^3(?:0[0-5]|[68][0-9])[0-9]{11}$ Discover: ^6(?:011|5[0-9]{2})[0-9]{12}$ JCB: ^(?:2131|1800|35\d{3})\d{11}$

  It depends. What type of number? What precision? What length? What do you want as a decimal separator? Etc. The following examples should help you want with the most common tasks. Positive integers of undefined length: ^\d+$ Positive integers of maximum length (10 in our example): ^\d{1,10}$ Positive integers of fixed length (5 in our example): ^\d{5}$ Negative integers of undefined length: ^-\d+$ Negative integers of maximum length (10 in our example): ^-\d{1,10}$ Negative integers of fixed length (5 in our example): ^-\d{5}$ Integers of undefined length: ^-?\d+$ Integers of maximum length (10 in our example): ^-?\d{1,10}$ Integers of fixed length (5 in our example): ^-?\d{5}$ Numbers of undefined length with or without decimals (1234.1234): ^-?\d*\.{0,1}\d+$ Numbers with 2 decimals (.00): ^-?\d*\.\d{2}$ Currency numbers with optional dollar sign and thousand separators and optional 2 decimals ($1,000,00.00, 10000.12, 0.00): ^$?\-?([1-9]{1}[0-9]{0,2}(\,\d{3})*(\.\d{0,2})?|[1-9]{...

  Never use a regular expression to validate a date. The regular expression is only useful to validate the format of the date as entered by a user. For the actual date validity, you should rely on another language. The following expressions will validate the number of days in a month but will NOT handle leap year validation; hence february can have 29 days every year, but not more. ISO date format (yyyy-mm-dd): ^[0-9]{4}-(((0[13578]|(10|12))-(0[1-9]|[1-2][0-9]|3[0-1]))|(02-(0[1-9]|[1-2][0-9]))|((0[469]|11)-(0[1-9]|[1-2][0-9]|30)))$ ISO date format (yyyy-mm-dd) with separators '-' or '/' or '.' or ' '. Forces usage of same separator accross date. ^[0-9]{4}([- /.])(((0[13578]|(10|12))\1(0[1-9]|[1-2][0-9]|3[0-1]))|(02\1(0[1-9]|[1-2][0-9]))|((0[469]|11)\1(0[1-9]|[1-2][0-9]|30)))$ United States date format (mm/dd/yyyy) ^(((0[13578]|(10|12))/(0[1-9]|[1-2][0-9]|3[0-1]))|(02/(0[1-9]|[1-2][0-9]))|((0[469]|11)/(0[1-9]|[1-2][0-9]|30)))/[0-9]{4}$ Hours and minutes, ...

  DOTALL is a flag in most recent regex libraries that makes the . metacharacter match anything INCLUDING line breaks. JavaScript by default does not support this since the . metacharacter matches anything BUT line breaks. To emulate this behavior, simply replaces all . metacharacters by [\S\s]. This means match anything that is a single white space character OR anything that is not a white space character! [\S\s]

  Metacharacters Character What does it do? $ Matches the  end of the input . If in multiline mode, it also matches  before a line break character , hence every end of line. (?:x) Matches 'x' but  does NOT remember the match . Also known as NON-capturing parenthesis. (x) Matches 'x' and  remembers the match . Also known as capturing parenthesis. * Matches the preceding character  0 or more times . + Matches the preceding character  1 or more times . . Matches  any single character except the newline character . ? Matches the preceding character  0 or 1 time . When used after the quantifiers *, +, ? or {},  makes the quantifier non-greedy ; it will match the minimum number of times as opposed to matching the maximum number of times. [\b] Matches a  backspace . [^abc] Matches  anything NOT enclosed by the brackets . Also known as a negative character set. [abc] Matches  any of the enclosed characters . Also known as a charac...
