Selenide - problem with PageObjects and fields

[Michał Paszek]

Hi,

I started using Selenide not that long time ago and I faced an issue (not sure if this is a bug or not, so haven't created one on github).

1) I have PageObject - LoginPage, with some fields:

private SelenideElement inputUsername = $("input[qxid='UserName']");
private SelenideElement inputPassword = $("input[qxid='PwField']");
private SelenideElement buttonLogin = $("*[qxid='LoginBtn']"); 

There are also respecitve standard getters in LoginPage and only default constructor. 

So this is something like a mix of Selenide and classic PO pattern.

According to Selenide documentation:

Defining SelenideElement doesn’t trigger the search in DOM yet, so you can save the locators in variables for later use at any place

so nothing should be wrong with my approach.

2) Then I have a test class LoginTest, with following test methods:

@Test
public void test1() {
    LoginPage loginPage = open("/", LoginPage.class);
    loginPage.getInputUsername().waitUntil(appears, 30000);
}

@Test
public void test2() {
    open("/");
    LoginPage loginPage = page(LoginPage.class);
    loginPage.getInputUsername().waitUntil(appears, 30000);
}

@Test
public void test3() {
    open("/");
    LoginPage loginPage = new LoginPage();
    loginPage.getInputUsername().waitUntil(appears, 30000);
}

test1 and test2 fail, only test3 works.

3) Stacktrace:

Element not found {by id or name "inputUsername"}

Expected: visible

I tried to do some debugging and find the root cause but I wasn't able to... 

I thought maybe the problem lays somewhere in SelenideFieldDecorator , as for below method we see first:

and later:

4) Interesting thing is that when I change the fields (everything else stays the same) to look like this:

@FindBy(how = How.CSS, using = "input[qxid='UserName']")
private SelenideElement inputUsername;

@FindBy(how = How.CSS, using = "input[qxid='PwField']")
private SelenideElement inputPassword;

@FindBy(how = How.CSS, using = "*[qxid='LoginBtn']")
private SelenideElement buttonLogin;

test1 and test2 pass. 

test3 fails but that's different issue (PageFactory.initElements() problem, discussed/described here: http://selenide.org/documentation/page-objects.html).

EDIT: Hmm is it? Is it different issue and not something related...?

5) Tools:

I am using Selenide 4.0 but with 4.2 it's the same. Selenium in version 2.53.

Tested on Chrome 55 (shouldn't matter).

So, I think that's all and I hope I described the problem well enough.

Let me know if you need any more details.

PS. There are of course some workarounds that can be applied for my issue (there always are) but that's not the point I guess :).

Hi Michal!

This is the problem described and fixed in pull request #443:

https://github.com/codeborne/selenide/pull/443

Shortly: since you use SelenideElement,  you don't need to use open("/", LoginPage.class nor page(LoginPage.class) methods.

Please upgrade to Selenide 4.2.1 - it contains the fix.

Hi Andrei,

Thanks for the answer.

Will consider upgrading to 4.2.1 but probably I'll simply drop using open and page methods..

Regards,

Michal
