When I run my collections ,sometimes I did not understand my test scipts results.For instances, if our test scipts defined wrong way I could not understand test failed or passed.

Hello there,
Check your console to see more info.
You can also add test to your test scripts.
You can read more about test over here.

Actually, my main problem is do not understand test scripts failures like in this post.If you dont use newman you cannot understand this failure in the postman interface.

.Conselo.log line is not a exist variable but in the test area you cannot see any negative commnets.
