    Jackal tools is an utility core library that manipulates Postman collections.

    This library has multiple features distinguished by the command parameter (see below). It combines collection items from Postman collections located in the source folder and appends into the target collection. The application is mainly focused on collection feature aggregations, and maintenance of single collections. All merge commands are using one output collection from many source collections, and the rest of the commands are one input collection to one output collection.

    How to use it

    Installing npm module

    npm i jackal-postman

    Using it in code

    const jackal = require("jackal-postman");
    //As one function call with a "command" parameter
    const executionMessage = await jackal.run("clr", "inputFile.json", "./sourceFolder", "outputFile.json", "./test/file1.json,./test/file2.json");

    Alternatively you can use each function separately from version 1.2.0 and up

    //Alternative for "ts" command
    const executionMessage = jackal.testsSmart("inputFile.json", "outputFile.json");
    //Alternative for "t200" command
    const executionMessage = jackal.tests200("inputFile.json", "outputFile.json");
    //Alternative for "clr" command
    const executionMessage = jackal.cleanRequests("inputFile.json", "outputFile.json");
    //Alternative for "clv" command
    const executionMessage = jackal.cleanVariables("inputFile.json", "outputFile.json");
    //Alternative for "mv" command
    const executionMessage = await jackal.mergeVariables("inputFile.json", "./sourceFolder", "outputFile.json", "./test/file1.json,./test/file2.json");
    //Alternative for "mr" command
    const executionMessage = await jackal.mergeRequests("inputFile.json", "./sourceFolder", "outputFile.json", "./test/file1.json,./test/file2.json");
    //Alternative for "mc" command
    const executionMessage = await jackal.mergeCollections("inputFile.json", "./sourceFolder", "outputFile.json", "./test/file1.json,./test/file2.json");
    //Alternative for "mev" command
    const executionMessage = await jackal.mergeVarsToEnvironment("inputFile.json", "./sourceFolder", "outputFile.json", "./test/file1.json,./test/file2.json");
    //Alternative for "amcv" command
    const executionMessage = jackal.appendMissingVariables("inputFile.json", "outputFile.json");
    //Alternative for "arph" command
    const executionMessage = jackal.appendRequestHash("inputFile.json", "outputFile.json");
    //Alternative for "ged" command
    const executionMessage = jackal.generateDescriptions("inputFile.json", "outputFile.json");
    //Alternative for "emd" command
    const executionMessage = jackal.exportMDDescription("inputFile.json", "outputFile.md");

    How does it work

    Merging commands

    Merge commands take initial file (or start with blank if not provided), take the features from the source folder collections or the set of provided collections and insert the features. The altered content is then saved in the output file.

    Using the merge commands

    Altering commands

    Altering commands take initial file, perform the command and save the altered content in the output file.

    Using the merge commands

    Commands options

    Command Meaning Behavior
    mv Merge collection variables Merges all variables from all source folder collections in the collection variables of the output collection
    mev Merge collection variables in an environment file Merges all collection variables from all source folder collections to an output environment file. If no source environment is specified, a blank one will be used as starting point
    mr Merge collection requests Merges all requests from all source folder collections into the output collection, collection variables are not transfered, only requests
    mc Merge collection in folders Merges each collection requests from all collections (from the source folder) in a separate folder in the output collection. Collection variables with this command are setup in the PreRequest script of each requests folder
    ts Append smart test assertions Adds response validation asserts to all requests of the source collection and saves to the output collection. Smart tests are generated by using the saved responses as examples in the collection. This command analyses the saved responses and creates tests to match those values. Currently this command supports only JSON and XML response testing. With this command, the sourceFolder is not used
    t200 Append HTTP 200 test assertions Adds test asserts (to check if response HTTP code is 200) to all requests of the source collection and saves to the output collection. With this command, the sourceFolder is not used
    clr Remove duplicate requests All repeating occurrences of absolutely the same requests (including name) will be removed, only one will remain. The remaining instance is the first occurrence that the cleanup algorithm encounters while analyzing. Scope of comparing duplicates is the whole collection with all folders and subfolders. With this command, the sourceFolder is not used
    clv Remove unused collection variables Removes all unused collection variables from the collection. It goes through the whole collection and looks for used variables. Then removes all collection variables that are not referenced anywhere in the collection. With this command, the sourceFolder is not used
    arph Append request payload hash Appends code in PreRequest code that hashes the request body with hashPassword variable value. This hash is then added to the request as PayloadHash header.
    amcv Append missing collection variables Appends missing collection variables that are referenced in any request, but are not present in the collection. With this command, the sourceFolder is not used
    gmd Generate MD descriptions in collection Generates MD descriptions on collection and requests, the description is in MD format and is saved in the output collection file. This command saves the MD descriptions in the collection file. To export these descriptions in a separate MD file use emd. With this command, the sourceFolder is not used
    emd Export MD document from collection Creates summary Markdown document from all the collection descriptions. This feature does not automatically generate descriptions. It only collects descriptions of all elements of the collection and creates one summary Markdown file. With this command, the sourceFolder is not used

    Commands can be combined by executing them one after the other and using the output collection of the first execution as a source collection of the next execution.

    Parameters

    Input file

    inputFile is considered any existing postman collection or postman environment file. This will will be the starting point to enhance with Jackal commands

    Source folder

    sourceFolder is a path on a local drive that will be used as a source of collections whos features will be added to the inputFile, see the commands above for more info.

    NOTE: the scanning of files in this folder is not recursive, only the *.json located directly into this folder will be considered for usage.

    Source collections

    sourceCollections is a substitute for sourceFolder. It is suppose to be a list of collection files separated with comma (,). If this parameter is present in the function call, the sourceFolder value is ignored.

    Output file

    outputFile is a path where we want the resulting collection/environment to be saved by the Jackal. This location should be accessible by the Jackal. This parameter is required in all use cases.

    Commands and needed parameters

    = Optional ✔️ = Required = Not used

    Command inputFile sourceFolder or sourceCollections outputFile
    mv Blank collection ✔️ ✔️
    mev Blank environment ✔️ ✔️
    mr Blank collection ✔️ ✔️
    mc Blank collection ✔️ ✔️
    clr ✔️ ✔️
    clv ✔️ ✔️
    t200 ✔️ ✔️
    ts ✔️ ✔️
    arph ✔️ ✔️
    amcv ✔️ ✔️
    gmd ✔️ ✔️
    emd ✔️ ✔️

    NOTES

    • The application will only append Collection Variables in the Output collection
    • You can use the Output collection as a Start collection, in this case only the new variables will be added and the Start collection will be overwritten
    • Source of Collection Variables/Requests are all the collections located in the Source folder
    • Duplicate (name and value) variables will not be added in the collection multiple times
    • If values are different in two same named variables then both will be added to the Output collection
    • Empty variables are not added
    • When using ts command, the source collection must have saved responses as examples, otherwise the generation does not work, there is nothing go analyze
    • When using the t* commands, the source collection is not altered in any way other than appending test assertions in the Test part of requests only. The assertions are added beside existing Test code.
    • This application does not alters source collections, the changes are only streamed to the output collection.
    • The mev command works with environment files, both the source and the output files are not collection files, but Postman environment files
    • sourceCollections is a substitute for sourceFolder. The commands that need these values at least one is mandatory (either or). It is useless to specify both, specifying sourceCollections overrides the sourceFolder value.
    • clr and clv are removing features from the inputFile and saves the cleaned up file in the outputFile
    • arph is self contained, it will not cause any problems if added and some values missing in the collection like thehashPassword
