I'm experiencing the same error despite code that seems correct otherwise.

Same here. on this and others. It's very frustrating.

I also have the same problem in this kata and another few... Could someone explain what does error say? Why solution is incorrect when all rows are the same as in expected table?

I'm having an issue where the last test is failing with the following message:

should should return the expected results
✘ expected true to respond to true? or perhaps you meant be true or be_truthy

But the expected and actual results match exactly? Any idea why this is?

I'm having this issue also. Fails on "Should return the expected results", but is also showing me the expected and actual results as the same four records in the same sort order?

should be a String value (1 Passed, 0 Failed)
Rows
should have 4 rows (1 Passed, 0 Failed)
should be sorted alphabetically (1 Passed, 0 Failed)
should should return the expected results
✘ expected true to respond to true? or perhaps you meant be true or be_truthy

Any idea what's going on?
