Package Semver-Constraint Check - Printing warnings condition not met

[Raghuchn]

Hello,

Have a requirement when version condition is not met using semver-constraints, how do i print an desired warning message.

Also, is it possible for the goss tool to continue with the rest of the commands after printing the warning.

package: ngin: installed: true versions: and:

• have-len: 1
• contain-element: semver-constraint: '>= 1.14.1'

Example: want to print a o/p like

WARNING invalid semver version bad: no major version found

---

Hello,

I am trying to use the semver-constraint for package check with the below format and it doesn't provide the intended output.

package: nginx: installed: true versions: and: -have-len: 1 -contain-element: semver-constraint: ">=1.14.1"

Error Thrown-

Error: Matcher expected array, got: map[%!t(string=-contain-element):map[%!t(string=matches):map[%!t(string=semver-constraint):%!t(string=>=1.14.1)]] %!t(string=-have-len):%!t(int=1)]

Any suggestion/help on how this condition needs to be handled.

Thanks in Advance!!

Tried the below it give me success, but the test case should have failed, as the version condition should not be met

[goss_validate]$ nginx -v
nginx version: nginx/1.14.1

[goss_validate]$ cat goss_packages.yaml
package:
  nginx:
    installed: true
    versions:
      and:
        - have-len: 1
          and:
           matches:
            semver-constraint: '<1.13.0'

Test Result:

Package: nginx: installed: matches expectation: [true] Package: nginx: version: matches expectation: []

Thanks!!

Hello, adding a note here in case someone runs into the same issue.

This looks like a typo in the test file, here's an example reproducing the error:

matching:
  example:
   content: ['1.14.1']
   matches:
     and:
       - have-len: 1
         and:
           matches:
             semver-constraint: '<1.13.0'

The correct syntax is:

matching:
  example:
   content: ['1.14.1']
   matches:
     and:
       - have-len: 1
       - semver-constraint: '<1.13.0'

output:

$ goss v
F

Failures/Skipped:

Matching: example: matches:
Expected
    ["1.14.1"]
to satisfy semver constraint
    "<1.13.0"

v0.4.2 is released with better error messages on syntax errors.

Thank you for reporting this, goss error messages are improved because of this issue!
