Allure not able to read output.xml file generated by AllureReportLibrary in Robot Framework

Question

I am using Ride (RobotFramework IDE) and I have imported Library AllureReportLibrary in my project. Using the Set Output Dir, I am creating a Directory C:/AutomationLogs/Allure and all the allure properties and xml files are getting generated in that path.

Set Output Dir   C:/AutomationLogs/

Then I am using the "allure serve C:\AutomationLogs\Allure" command to try and generate the html report file in command prompt, but it shows the below error -

"Could not read result C:\AutomationLogs\Allure\f56f4796-d30a-47f3-a988-d17f6c4e13ca-testsuite.xml: {} com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize va lue of type ru.yandex.qatools.allure.model.SeverityLevel from String "None": value not one of declared Enum instance names: [trivial, blocker, minor, normal, critical]"

The xml file "f56f4796-d30a-47f3-a988-d17f6c4e13ca-testsuite.xml" was generated using the AllureReportLibrary

Also the index.html file which is generated after the command opens after this command and shows Allure Report unknown unknown - unknown (Unknown) 0 test cases NaN%

I am using the below - Allure version - 2.4.1

Ride version - RIDE 1.5.2.1 running on Python 2.7.12.

I am new to Robot Framework and Allure. Please let me know whether I have implemented it correctly and why I am facing the above error.

Answer 1

I'm using the 1.1.1 version of Allure Adaptor for Robot Framework and the severity is picked from the test case tags and added as a label under the test-case element of the report.

However, it seems that Allure 2.6.0 is also expecting a valid value for the severity attribute of the test-case element.

In order to use Allure2 with the current reports I have altered AllureListener.py to also add the severity to the test case:

elif tag in SEVERITIES:
    test.severity = tag
    test.labels.append(TestLabel(
        name='severity',
        value=tag
    ))

How to create the Allure reports in Robot Framework ?

Initially, Download the Command line and UNzip the file and save the path of the bin folder in environment.

Link : http://repo.maven.apache.org/maven2/io/qameta/allure/allure-commandline/2.8.0/allure-commandline-2.8.0.zip

Unzip the above file then put it in the Environment folder.

Then Pip install the below modules

1. pip install allure-robotframework
2. pip install robotframework-allurereport

In robot file, Add the Library in Settings like, Example :

Library AllureReportLibrary D:\eclipse\RobotFramework\results

Then Use the Below commands to run the robot code.

robot --listener allure_robotframework;D:\eclipse\RobotFramework\results Example.txt

Finally,

Generate the HTML file by,

allure generate D:\eclipse\RobotFramework\results

Note : Use the same path what you used in the previous command to generate the HTml.file. and Open in Mozhila FireFox. It wont be work in Chrome. I dont know exactly why.

If your output.xml has severity = None for any testcase then the allure-robotframework-adaptor will give the error that you have mentioned. Creating TestCase() object with severity='' in start_suitesetup method of AllureListener.py will do the trick.

def start_suitesetup(self, name, attributes):
    ....
    ....
    test = TestCase(name=name,
                    description=description,
                    start=now(),
                    attachments=[],
                    labels=[],
                    parameters=[],
                    steps=[],
                    severity='')
