[Question] executeJS action

[mmularski]

Hello
I need help with <executeJS> action.
Is it possible to get value from executed JS via <executeJS> action and pass it in different action?

I need something like example attached in documentation $myVar = $I->executeJS('return $("#myField").val()');
I know about <grabTextFrom> action, but before grabbing value I need to process it.

Hi @mmularski , could you try next code:

<amOnPage url="/" stepKey="navigateToStorefront"/>
<waitForPageLoad stepKey="waitHomePageLoad"/>
<executeJS function="return window.innerWidth" stepKey="execJs"/>
<assertNotEmpty stepKey="assert">
    <actualResult type="string">$execJs</actualResult>
</assertNotEmpty>

@mmularski Yes it is possible to grab the value from an <executeJS> action.
The code block provided by @ameysar is correct, but just to add onto it, you can use the returned data like you would any grab* action:

<grabValueFrom stepKey="grabbedText" selector=".selector"/>
<comment userInput="Here is my grabbed text: {$grabbedText}" stepKey="showThatWeGrabbedIt"/>

@ameysar @KevinBKozan following code does not work for me:

<executeJS function="return (jQuery('.page-title').text().substring(1))" stepKey="invoiceNumber2"/> <fillField userInput="$invoiceNumber2" selector="{{StorefrontCustomerMyOrdersSection.invoiceNumberFilter}}" stepKey="fillInvoiceNumber"/>

It generates PHP like:
$I->executeJS("return (jQuery('.page-title').text().substring(1))"); $I->fillField("#invoice-number", "$invoiceNumber2");

but $invoiceNumber2 is not defined. I need something like:
$invoiceNumber2 = $I->executeJS("return (jQuery('.page-title').text().substring(1))"); $I->fillField("#invoice-number", "$invoiceNumber2");

@mmularski which version of magento2-functional-testing-framework do you use ? Provided example works on 2.2.0 and above. If you are using version lower than 2.2.0 code for executeJs will be generated without return value and in version >= 2.2.0 executeJs will have return value

[mmularski]

@ameysar That might be this. I use MFTF 2.1.2, but when I'm trying to update to version 2.2.0 and generate a suite I got an error:

@mmularski please check documentation. Before generating tests you should build project by next commant
vendor/bin/robo build:project

[mmularski]

@ameysar vendor/bin/robo build:project does not fix the problem.
removing vendor/, composer.lock and composer install command too. Everything I've done with documetation.

Edit:
After adding MAGENTO_BP to .env file, suite has generated successfully, and variable has been created for <executeJs> action, thank you :)
