How to Use "while ..." Command in Selenium IDE for Chrome?

When using "while ..." Commands in test steps in Selenium IDE for Chrome, you need to remember the following:

1. Use "while ... end" to form a loop block of test steps.

2. Use JavaScript Boolean expression syntax to specify conditions to "while" commands.

3. ${variable} is allowed in condition expressions.

4. You can use "execute script" command in loop block to update the loop condition control variable in ${variable} format. But Selenium IDE variables are considered as text strings. You need to convert them to number, if needed.

Here is a sample test called "While" on how to use variables:

1  store | 0 | sum
2  store | 1 | count
3  while | ${count} <= 10
4     execute script | return Number(${sum}) + Number(${count}); | sum 
5    execute script | return Number(${count})+1; | count
6  end
7  echo ${sum}

Here is the log output when you execute the above test.

1. store on 0 with value sum OK
2. store on 1 with value count OK
3. while on ${count} <= 10 with value 100 OK
4. executeScript on return Number(${sum}) + Number(${count}); with value sum OK
5. executeScript on return Number(${count})+1; with value count OK
6. end OK
echo: 55
