Suppressing error for further chained .find() commands

[dikwickley]

Fixes: #4079

Solves the third point from this comment (#3991 (comment))

Further chained .find() commands should not throw the Timeout or any other error again. Ex. in browser.element('.invalid-selector').find('selector').getText();, there should only be one error due to browser.element() and .find() should not throw an error again (suppress the error for it).

Thanks in advance for your contribution. Please follow the below steps in submitting a pull request, as it will help us with reviewing it quicker.

• Create a new branch from master (e.g. features/my-new-feature or issue/123-my-bugfix);
• If you're fixing a bug also create an issue if one doesn't exist yet;
• If it's a new feature explain why do you think it's necessary. Please check with the maintainers beforehand to make sure it is something that we will accept. Usually we only accept new features if we feel that they will benefit the entire community;
• Please avoid sending PRs which contain drastic or low level changes. If you are certain that the changes are needed, please discuss them beforehand and indicate what the impact will be;
• If your change is based on existing functionality please consider refactoring first. Pull requests that duplicate code will most likely be ignored;
• Do not include changes that are not related to the issue at hand;
• Follow the same coding style with regards to spaces, semicolons, variable naming etc.;
• Always add unit tests - PRs without tests are most of the times ignored.

@garg3133 is this a good solution to suppress the error for chained find commands

Can you add a test to show that this works as anticipated

Hey, Have you tried the solution on some test cases ?
I ran this over a test case which is
browser.element.find('.invalid_selector').getProperty('innerHTML');

In my case it still didn't suppress the further errors.

hey @chikara1608
The example you posted is not a further find command, there is only one single find.
see this #3991 (comment)

try it for such an example

browser.element('.invalid_selector').find('.some_other_selector')

hey @AutomatedTester how can I add such test case that checks for the errors thrown.
can you point to some test that checks for the error thrown (I tried looking in web-element tests but couldn't find)

[chikara1608]

ohh my bad! So if I got this right, the solution would basically suppress the error thrown by find in case there was an error in the command before it right ?
But it would still throw error in the command after the find command (for now at-least) right ?
For ex : browser.element('.invalid-selector').find('selector').getText();
This test case throws error at .element as well as .getText but suppresses the find error.

Yes correct
