Selenium: Implicit vs Explicit Waits

SELENIUM IMPLICITVS EXPLICITWAITS

INTRODUCTION INTRODUCTION INTRODUCTION

AJAX TECHNIQUES DOMINATE, LEADING TO THE ASYNCHRONOUS LOADING OF WEB ELEMENTS AT DIFFERENT

INTERVALS. THIS ASYNCHRONOUS BEHAVIOR OFTEN POSES A CHALLENGE WHEN IT COMES TO LOCATING AND INTERACTING WITH ELEMENTS.

IMPLICITWAITS

IMPLICIT WAITS IN SELENIUM WEBDRIVER

ARE A MECHANISM THAT TELLS THE WEB DRIVER TO POLL THE DOM FOR A CERTAIN AMOUNT OF TIME WHEN TRYING TO LOCATE ELEMENTS.

IMPLICIT WAITS ARE SET FOR THE LIFE OF THE WEBDRIVER INSTANCE AND APPLY TO ALL SUBSEQUENT INTERACTIONS WITH THE DOM.

EXPLICITWAITS

EXPLICIT WAITS HELP ENSURE THAT THE TEST SCRIPT WAITS FOR AN ELEMENT TO BE VISIBLE, CLICKABLE, OR MEET A CUSTOM CONDITION BEFORE CONTINUING. THIS IMPROVES TEST STABILITY AND RELIABILITY, ESPECIALLY WHEN DEALING WITH DYNAMIC WEB PAGES OR SLOWLOADING ELEMENTS.

WHEN EXPLICIT WAIT VALUE >= IMPLICIT WAIT VALUE:

BEHAVIOR:

WEBDRIVER INITIALLY WAITS FOR IMPLICIT WAIT MAX TIME TAKEN IS EQUAL TO EXPLICIT WAIT VALUE

EXAMPLE AND TIMING:

CODE SNIPPET AND EXECUTION TIMING

WHEN EXPLICIT WAIT VALUE < IMPLICIT WAIT VALUE:

BEHAVIOR:

MAX TIME TAKEN VARIES

BETWEEN IMPLICIT WAIT VALUE AND (IMPLICIT WAIT VALUE + EXPLICIT WAIT VALUE)
