Watir Rspec Table Cell

Now I have the problem that I can identify the text in a table.

For this Site I choose from

1. Paperback
2. weiß 90g
3. 12 cm x 19 cm
4. number of pages: 24
5. Click "Cover berechnen"

Test with test::unit okay

assert(@browser.th(:text => "Buchrückenbreite").exists?)
assert(@browser.td(:text => "0.13 cm").exists?)

Test with rspec incorrect

@browser.th(:text => "Buchrückenbreite").should == true
@browser.td(:text => "0.13 cm").should == true

Error Message:

expected: true
     got: #<Watir::TableHeaderCell:0x..fc61f5c1d071c696a located=false selector={:text=>"Buchrückenbreite", :tag_name=>"th"}> (using ==)

Another test:

expect(@browser.th(:text => "Buchrückenbreite")).to be_true

Error Message:

expected #<Watir::TableHeaderCell:0x007fd9452034d0> to respond to true?

If you want to check if an object exists, you can use RSpec's exist matcher.

In the 'should' syntax:

@browser.th(:text => "Buchrückenbreite").should exist
@browser.td(:text => "0.13 cm").should exist

Or in the 'expect' syntax:

expect(@browser.th(:text => "Buchrückenbreite")).to exist
expect(@browser.td(:text => "0.13 cm")).to exist
