2、ssonSelenese Commands32Discover the automating power of SeleniumVariable Substitution#1 You can store any value into a variable using selenium accessors. Variable substitution provides a simple way to include a previously stored variable in a command parameter If you give the variable name as intAmo
3、unt. To use the variable anywhere else use $intAmount. This will substitute the actual value in the place of $intAmount. Use echo $intAmount to display the values in the Log. Any of the selenium accessors can be used to store a value. Some of the key accessors are storeText, storeValue, storeCookie,

Create a test case by opening FirefoxToolsSelenium IDE (by default it is in Recording mode)3. Update the base URL of Selenium IDE with the URL in the Firefox address4. C
5、lick on the link “Click here to enter your name”, when prompter for your name, enter your name.5. Your name will be displayed in next line.6. Highlight your name Right click and select the assertText, then Stop the recording in Selenium IDE.7. Rerun the test case in Selenium IDE4Discover the automat

Try to run multiple time and make sure your test case is passed without any failures.3. Now save the test case as “Recorded_TestCase_HelloWorld.html”4. Double click and op

Make sure it precedes otherwise your test case will fail.5Discover the automating power of SeleniumVariable Substitutio

11、storedVars#1 All the variables are internally stored in a map named “storedVars”. storedVars allows you to access the $varName using the “varName” key within the map. Using storedVars you can reference the values within Javascript Evaluation code. What is a Map? Maps provide a more general way of st
12、oring elements. An object that maps keys to values. A map cannot contain duplicate keys (duplicate variable names); The Map collection type allows to store pairs of elements, termed “keys“ and “values“, where each key maps to one value. Here Keys refers Selenium variable Names and values refers to t
