BTW - on a related note, I was seeing this failure in the tests:

Test checks for PG data-types output

Traceback (most recent call last):

AssertionError: ARRAY[1, 2, 'nan']::float[] does not match with 1, 2, 'nan'

Yes this issue is already logged in redmine. When we execute SELECT ARRAY[1, 2, 'nan']::float[]; from Query tool, we don't get output. The "Data Output" panel remains blank and in message panel we get  {"info":"","success":1,"errormsg":"","data":{"rows_affected":1,"result":[[[1.0,2.0,NaN]]],"additional_messages":null,"status":"Success"},"result":null}.

Due to this error, I have executed different query for each value. If I run a single query, the test case fails and I can't get the desired output.

I have also tried to clear the SQL editor for each query and avoid loading Query tool for their respective call but I couldn't.

I will work on your other suggestion.

Hi,

As we have been facing many issues with different data-type display in Query Tool output, Dave suggested to write the feature test for the same.

I have started with some basic set of data-type values and will add more.

Please find the attached initial patch for the same.

Some thoughts:

- Instead of sleeping, which is almost always a bad design, can we wait for objects to appear?

- Currently you're testing each datatype with an individual query, e.g.

SELECT 32768;

I would suggest we test all datatypes at once, e.g.

SELECT 32768, 43723489023489, '2017-09-12 15:34:11', 12345.56;

etc. That will massively reduce the time taken to execute the tests (which is a big concern).

- Shouldn't we be casting the values in the SELECT, so we (and the database) know exactly what we're expecting? e.g.

SELECT 32768::int, 43723489023489::bigint, '2017-09-12 15:34:11':timestamp, 12345.56::numeric(8,4);

That would also allow us to verify the type name displayed in the column headers.

Thanks!
