karate-grpc's Issues

Unable to run karate-grpc - generation of protobuf descriptor sets fails

Creation of the Public grpc client failing

Hi @thinkerou ,

I am trying to start run a dummy grpc client using the following command:
java -cp .:gson.jar:grpc-netty.jar:grpc-protobuf.jar:grpc-stub.jar:protobuf-java-util.jar:karate-grpc-core.jar:karate.jar: com.intuit.karate.netty.Main find . -name 'helloworld.feature'

This includes the karate-grpc-core and its dependencies. This makes a call into the Java Interop but fails while the public client.

The grpc server is running on a privatye IP and the code snippet is attached for your reference:

Feature: grpc helloworld example
Background:
* def Client = Java.type('com.github.thinkerou.karate.GrpcClient')
* def client = Client.create('10.223.4.142', 50051)
Scenario: do it
* def payload = read('requests/helloworld.json')
* def response = client.call('helloworld.Greeter/SayHello', payload)
* def response = JSON.parse(response)
* print response
* match response[0].message == 'Hello ALL'
* def message = response[0].message

Can you help me out here?

JsonFormat parse fail

proto likes:

message {
  string message = 1;
  string address = 2;
}

input likes:

[

  }
]

when calls JsonFormat.parser().merge() will have the following error:

Can't extract full service from the java class

Hi @thinkerou,
I have switched to maven environment and am running a grpc server locally. I have compiled the proto files and stored them in the same package as the feature files, but while trying to run the test, during the call step it says that javascript evaluation failed with the following error, could you help out the right way to mention the service name?
Call command:
* def response = client.call('github.com.Juniper.contrail.pkg.services.DiscoverResourceExecute', template_request)

Error:
com.intuit.karate.exception.KarateException: dms_api_test.feature:13 - javascript evaluation failed: client.call('github.com.Juniper.contrail.pkg.services.DiscoverResourceExecute', template_request), Can't extract full service from github.com.Juniper.contrail.pkg.services.DiscoverResourceExecute
Regards

Google proto import issues

Hello @thinkerou

I have a proto file which imports Google proto, These were added so that it Grpc can also be hosted as REST endpoints. Though highly unnecessary, it remains in our proto file.

So I cannot use these proto files directly, Can you see if we can have this generate code for karate-grpc automation.

syntax = "proto3";

package myproto;

import "google/api/annotations.proto";


service myservice {
    rpc AnewServiee (MyRequest) returns (MyResponse) {
        option (google.api.http) = {
      post: "/mygrpcrest/AnewServiee"
      body: "*"
    };
    }
}


    message MyRequest {
        string id = 1;
    }

    message MyResponse {
        string id = 1;
        string title = 2;
        string parentId = 3;
    }

How to add support for thrift service without grpc

How to create Grpc client with https connection?

Hi @thinkerou,
I have a Grpc server running in https mode, so i need to make call from karate tool.
is it possible? if yes then how?

Enable support to find protobin files from jars

The current implementation of this library basically expects to find the .protobin in the file system. This is fine if the number of proto files are less, but when this count starts increasing the code generator which translates .proto to .java basically takes a lot of time and as such one would want these to be part of a separate Maven/Gradle module, which comes in as a dependency.

Now the problem here is that karate-grpc is not aware of the .protobin that can be embedded in the proto jar.

I have solved this in an internal fork of this codebase, but I was wondering if you are open to basically accomodating that here so that I dont have to maintain my own copy.

@thinkerou - Let me know what you think and I can try and raise a PR that enables this support.

karate-grpc-demo: Use in-memory redis instead of relying on installed/deployed redis instance

Using https://github.com/fppt/jedis-mock instead of requiring an installed instance of redis would significantly lower the barrier to entry.

Why require infrastructure/installs for an in-memory cache? A library dependency is far easier to deploy, especially for CI infrastructure.

While starting managed channels on client we get error: `Channel for target was not shutdown properly!!!`

When run bi-stream.feature case I get the follow error:

java: incompatible types error on compiling helloworld

Hi @thinkerou

I am getting the following error when I try to compile your basic Helloworld package

Error:(34, 67) java: incompatible types: java.util.List<gherkin.formatter.model.Feature> cannot be converted to java.util.List<com.github.thinkerou.demo.helloworld.Feature>
Error:(71, 39) java: incompatible types: java.util.List<com.github.thinkerou.demo.helloworld.Feature> cannot be converted to java.util.List<gherkin.formatter.model.Feature>

karate-grpc maintained

Is this still maintained? I was using karate for api testing but now I need something to test grpc aswell

Unable to consume the latest released version

Following are the steps that I am following:

Create a new project using the command mvn archetype:generate
After the template project has been created I am basically updating the dependencies to

<dependency>
  <groupId>com.github.thinkerou</groupId>
  <artifactId>karate-grpc-core</artifactId>
  <version>1.0.3</version>
  <scope>test</scope>		  
</dependency>

Now when I run mvn dependency:resolve I get the below error

[ERROR]

It looks like there's something wrong with the publishing of the grpc-parent pom file.

I went back and checked https://repo1.maven.org/maven2/com/github/thinkerou/karate-grpc-parent/ and noticed that 1.0.3 does not exist there.

Would this need a new release to get this sorted out ? Or maybe just attempt a release for 1.0.3 karate-grpc-parent alone ? Basically re-run the release job, so that it passes for the parent-pom but fails for everything else since those versions are already there?

Hope give more detail info for part: testing-grpc-server in README.md

can you give more info in README.md about this chapter: https://github.com/pecker-io/karate-grpc#what-to-need-for-testing-grpc-server .

how or where to input gRPC server
how to where to place the protobuf file

thanks

Need to call grpc service with custom header as Metadata

Hi Team,

Need to call grpc service with custom header (JWT token) as metadata along with request, so anyone know how can i pass it through karate?

Unable to consume latest version

I get same errors as user was experiencing on #22
I see same error on versions 1.0.3, 1.0.4, 1.0.5

PR for fix: #25

Run test error

when run test it errors using the command:

$ mvn clean compile package -Dmaven.test.skip=true 
$ cd karate-grpc-demo
$ mvn test

error info:

grpc java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;CLjava/lang/Object;)V

Using SSL certificate in Karate-gRPC. Caught exception while waiting for rpc

Hi,
Thanks for sharing this implementation. I am trying to automate a gRPC service call following the example documented here. My feature file looks like below

Feature: DeterminationAPI GetTax

  Background:
    * def Client = Java.type('com.github.thinkerou.karate.GrpcClient')
    * def client = Client.create('eg-gtp-tax-engine-adapter-mvp-grpc.kmc-default.us-west-2.test.beardsley.abc.com',443)

  Scenario: do it
    * def payload = read('getTax.json')
    * def response = client.call('com.abc.tax.amounts.v1beta1.DeterminationAPI/getTax', payload)
    * def response = JSON.parse(response)
    * print response

I have included the jar file which has the .proto file of the gRPC service (e.g. com.abc.tax.amounts.v1beta1.DeterminationAPI). However, I am getting the below error.

Jun 08, 2021 12:01:51 AM com.github.thinkerou.demo.helloworld.HelloWorldServerMain start

	at ✽.* def response = client.call('com.abc.tax.amounts.v1beta1.DeterminationAPI/getTax', payload) (determinationAPI.feature:8)

Can you please help troubleshooting this issue?

Thanks for your attention @thinkerou
