There are 7 usable RESTful API endpoints defined in the schema configuration
There are 5 endpoints which have errors and will not be handled in the test generation

The problem is related to:

package org.evomaster.core.problem.rest
- In file: RestActionBuilderV3.kt
  - In function: handleBodyPayload()

Followig part of the code: val bodies = body.content.filter { if (it.value.schema == null) { false } else { val reference = it.value.schema.$ref reference.isNullOrBlank() || getLocalObjectSchema(swagger, reference) != null } }

When OAS3 specification is following:

    post:
      tags:
        - organization
      summary: Creates a Organization
      description: This operation creates a Organization entity.
      operationId: createOrganization
      parameters:
        - $ref: '#/components/parameters/Fields'
      requestBody:
        $ref: '#/components/requestBodies/Organization_FVO'
      responses:
        '201':
          $ref: '#/components/responses/201Organization'

    Organization_FVO:
      description: The Organization to be created
      content:
        application/json:
          schema:
            $ref: '#/components/schemas/Organization_FVO'
      required: true

requestBody's content (body.content) is of course null as it cotains a reference $ref to Components->Request Bodies ($ref: #/components/requestBodies/Organization_FVO') hence following error: "Fail to parse endpoint POST/partyManagement/v5/organization due to body.content must not be null"

Maybe suggestion to fix it as following:

val bodies: Map<String, MediaType> = body.content?.filter {
            it.value.schema != null && (it.value.schema.`$ref`.isNullOrBlank() || getLocalObjectSchema(swagger, it.value.schema.`$ref`) != null)
        } ?: emptyMap()

Hi @aruvic ,

thanks for reporting this bug. You are indeed right. Dealing with requestBody.$ref is definitively something we should handle

aruvic commented 2 months ago

Hi @arcuri82, thanks for confirming it.

I tried to fix it myself as below:

import io.swagger.v3.oas.models.parameters.RequestBody

    private fun resolveRequestBody(swagger: OpenAPI, reference: String): RequestBody? {
        val classDef = extractReferenceName(reference)
        return swagger.components.requestBodies[classDef]
    }

    private fun handleBodyPayload(
            operation: Operation,
            verb: HttpVerb,
            restPath: RestPath,
            swagger: OpenAPI,
            params: MutableList<Param>,
            options: Options) {

        // Return early if requestBody is missing
        val body = operation.requestBody ?: return

        // Ensure the verb is appropriate for operations with a body
        if (!listOf(HttpVerb.POST, HttpVerb.PATCH, HttpVerb.PUT).contains(verb)) {
            log.warn("In HTTP, body payloads are undefined for $verb. Issue in $restPath")
            return
        }

        // Handle dereferencing if requestBody is referenced
        val resolvedBody = if (body.`$ref` != null) {
            resolveRequestBody(swagger, body.`$ref`) ?: return
        } else {
            body
        }

        // Extract content, ensuring it's not null or empty
        val bodies: Map<String, MediaType> = resolvedBody.content?.filter { entry: Map.Entry<String, MediaType> ->
            entry.value.schema?.let { schema ->
                !schema.`$ref`.isNullOrBlank() && getLocalObjectSchema(swagger, schema.`$ref`) != null
            } ?: false
        } ?: emptyMap()

        if (bodies.isEmpty()) {
            log.warn("No valid body-payload for $verb:$restPath. Defaulting to empty handling.")
            return
        }

        // Proceed with first valid MediaType found
        val obj: MediaType = bodies.values.first()
        var gene = getGene("body", obj.schema, swagger, referenceClassDef = null, options = options)

        // Wrap gene as optional if not explicitly required
        if (!(resolvedBody.required ?: false) && gene !is OptionalGene) {
            gene = OptionalGene("body", gene)
        }

        val contentTypeGene = EnumGene<String>("contentType", bodies.keys.toList())

        // Add to parameters list
        params.add(BodyParam(gene, contentTypeGene))
    }

I also tried to improve "responses" as following by adding:

import io.swagger.v3.oas.models.responses.ApiResponse
    private fun resolveResponse(swagger: OpenAPI, responseOrRef: ApiResponse): ApiResponse {
        responseOrRef.`$ref`?.let { ref ->
            val refKey = extractReferenceName(ref)
            return swagger.components.responses[refKey] ?: responseOrRef
        }
        return responseOrRef
    }

and in function handleOperation() changed the code to be like this:

            val produces = operation.responses?.entries?.mapNotNull { entry ->
                val response = resolveResponse(swagger, entry.value)
                if (response.content != null && response.content.isNotEmpty()) {
                    response.content.keys
                } else null
            }?.flatten()?.toSet()?.toList() ?: listOf()

provided I did everything correct above (I'm not sure, please check), I get now another error:

Do I need to open a new bug for the above error?

Hi, thanks for reporting this. No need to open a different bug report for this, at least for now, as it might be a side-effect of your changes. Unfortunately this week is quite busy :( I will see to look into it in more details hopefully next week

thanks a lot

arcuri82 commented 2 months ago

@aruvic I made a fix for the handling of dereferencing. but i m waiting for CI to finish before merging it into master branch (I ll write it here once that is done). anyway, the other reported issue (mismatched gene impact) seems unrelated to this, ie, it is another bug.

@man-zhang any guess of why it could happen? as a temporary workaround, do we have any way to disable collecting gene impact?

also, not sure how best to address this bug, as it might be difficult to reproduce... @aruvic is that API closed-source? if so, @man-zhang we might need some more logging to understand what is going on

thx!

arcuri82 commented 2 months ago

a fix for dereferencing is now merged in the master branch.

@aruvic could you check if it fixes the first issue you reported? if so, could you check if you still get the error on mismatched gene impact? (likely yes, as they seem unrelated). In such case, can you open it in a different issue? thx!

Hi, sorry, I was out of office for the last two weeks. Indeed I can confirm that the first issue is fixed and the second issue still persists for which I will open a separate issue.
