FileNitFound exception when attempting to run a test case

[Johnzie]

Hi ,

I am very new to Talend and trying to add a basic test case to a Tmap component that basically concatenates the FirstName and LastName from a source file and prints to a tLogRow component.

After creating a new test case, I added the input file and reference file to the default test instance.

However , when attempting to run from the Run view , I get the below error

Seems like the input file and reference file selection is not reflected in the Run View.

Am using Talend Studio 7.3.1 and have an active subscription

A quick update, I managed to set the file in the Contexts view and now the test seems to run and shows a files differ message. where can I see the actual differences between expected and actual values ? my reference file matches the expected output but I am unable to figure out what is the mismatch

When I run the test , I see this error

Hi

tFileCompare compares two files and returns a boolean value to indicates the files differ or are identical' in a global variable, it does not show the actual differences, you have to check it manually or through tool, such as https://www.diffchecker.com/diff.

Thanks Shong,

In a test case, where is the actual output saved so I can compare it with my expected file ?

It all seems to happen in-memory

Thanks

John
