How to test for blank text field when using robotframework-selenium?

Question

How can I specify blank/empty value for a text field when using the robotframework-seleniumlibrary with a TSV file? For example, I have the following:

Textfield          


        

Answer 1

Yes, ${EMPTY} is a built in variable.

There are many examples, see an example here

Answer 2

You can use either a single backslash \ or special variable ${EMPTY} to create an empty string in the test data. User guide has the details: Robot Framework User Guide.

Answer 3

${EMPTY} is good for a blank value but, surprisingly, it didn't work for an empty value.

I found what I was looking for. The field I was verifying had no value in its value attribute and I wanted to verify it. It was returning '' as the value and when using ${EMPTY} it couldn't find '''' instead. Such a minor thing but ended up solving what I needed, so it depends what you're seeking to verify.
