NPM: peer dependency is not detected for global packages

 


Issue: In npm, peer dependency is not detected for global packages like when you try to install "newman" and then install "newman-reporter-htmlextra" so that you can run Postman/Newman tests collection with htmlextra reporter, it keeps failing because no suitable Newman version is found:

  • npm install -g newman
  • npm install -g newman-reporter-htmlextra
  • newman run "Publish.postman_collection.json" -e QAUS.postman_environment.json -r htmlextra --reporters cli,junit,htmlextra  --reporter-htmlextra-export TestReport.html

You may get this error:

"npm WARN newman-reporter-htmlextra@1.20.4 requires a peer of newman@^5.1.2 but none is installed. You must install peer dependencies yourself"

Solution: Peer dependency and the required package should be installed together like:

  •  npm install -g newman newman-reporter-htmlextra

The use of Verbose attribute in testNG or POM.xml (maven-surefire-plugin)

At times, we see some weird behavior in your testNG execution and feel that the information displayed is insufficient and would like to see more details. At other times, the output on the console is too verbose and we may want to only see the errors. This is where a verbose attribute can help you- it is used to define the amount of logging to be performed on the console. The verbosity level is 0 to 10, where 10 is most detailed. Once you set it to 10, you'll see that console output will contain information regarding the tests, methods, and listeners, etc. <suite name="Suite" thread-count="5" verbose="10"> Note* You can specify -1 and this will put TestNG in debug mode. The default level is 0. Alternatively, you can set the verbose level through attribute in "maven-surefire-plugin" in pom.xml, as shown in the image. #testNG #automationTesting #verbose # #testAutomation

Encode/Decode the variable/response using Postman itself

We get a lot of use cases where we may have to implement Base64 encoding and/or decoding while building our APIs. And, if you are wondering if it is possible to encode/decode the variable/response using Postman itself or how to encode/decode the token or password in postman and save it in a variable? To Base64 encode/decode, the quickest way is to use JavaScript methods btoa, atob: atob - It turns base64-encoded ASCII data back to binary. btoa - It turns binary data to base64-encoded ASCII. Sample code : var responseBody = pm.response.json(); var parsedPwd = JSON.parse(atob(responseBody.password)); // presuming password is in the payload pm.collectionVariables.set("password", parsedPwd);
