I have a scenario, where an API(Provider1) consumed by GUI(Consumer1) and at the same time Provider1 Application wants to consume(Consumer2) another API(Provider2) to cater the Consumer1 request. How to test this scenario with PACT.
GUI(Consumer1) -> MicroService (Provider1 & Consumer2) - Another MicroService(Provider2).
I’d read https://docs.pact.io/provider/readme#stub-calls-to-downstream-systems and the gist associated with it. I think it answers your question

Using MassTransit.RabbitMQ v5.3.2 and OpenTracing.Contrib.NetCore v0.5.0.
I'm able publish and consume events to RabbitMQ using MassTransit and I've got OpenTracing working with Jaeger, but I haven't managed to get my OpenTracing TraceIds propogated from my message publisher to my message consumer - The publisher and consumer traces have different TraceIds.
I've configured MassTransit with the following filter:
cfg.UseDiagnosticsActivity(new DiagnosticListener("test"));
I'm not actually sure what the listener name should be, hence "test". The documentation doesn't have an example for OpenTracing. Anyways, this adds a 'Publishing Message' span to the active trace on the publish side, and automatically sets up a 'Consuming Message' trace on the consumer side; however they're separate traces. How would I go about consolidating this into a single trace?
I could set a TraceId header using:
cfg.ConfigureSend(configurator => configurator.UseExecute(context => context.Headers.Set("TraceId", GlobalTracer.Instance.ActiveSpan.Context.TraceId)))
but then how would I configure my message consumer so that this is the root TraceId? Interested to see how I might do this, or if there's a different approach...
Thanks!
If anyone is interested; I ended up solving this by creating some publish and consume MassTransit middleware to do the trace propagation via trace injection and extraction respectively.
I've put the solution up on GitHub - https://github.com/yesmarket/MassTransit.OpenTracing
Still interested to hear if there's a better way of doing this...
I am working for my client using Asp.net webAPI2 and angularJS. Now my client have following requirement,but i am unable to understand what type of project i have to create like WebAPI project,window service or any other? Anyone please tell me what the client actually want and how can i do it?
QueueManager will need to be some kind of a service which would be able to run jobs on a timed basis. We envision it being a service that runs on a continuous loop, but has a Thread.Sleep at the end of each iteration with a duration of x-seconds (“x” being set in a config file.) You should create this QueueManager service as a new project within the Core.Jobs project; I would like to have the project name be “Core.Jobs.QueueManager”, along with the base namespace.
Here are the functions that the QueueManager will do for each iteration:
1) Do a worker healthcheck (JobsAPI: Queue/WorkerHealthCheck – already created)
a. This method will just return a 200 status code, and a count of workers. Not need to act on the return value.
Look at Hangfire, it is quite easy to set up and simple to use.

does a codedui tests agent exposes an api to get information
about it's status in real time?
if so where can i find details about it and purhapse code examples?
edit:
i've found a way to get some information on test agent via command line (link in the comment section),
still would love to know id there's an api to enable other types or actions, specifically restarting the agent
Looks like there is a lot of functionality to be accessed through TestAgentConfig.exe. I found an MSDN blog post that goes into some details on the feature.
Specifically, to start or stop the agent: "Start/Stop service - sc \machinename stop vsttagent ; sc \machinename start vsttcontroller. If the agent and controller are in different domain, you can use IP instead of machine name."
How to get the user who initiated the process in IBM BPM 8.5. I want to reassign my task to the user who actually initiated the process. How it can be achieved in IBM BPM?
There are several ways to get that who initiated a Task , But who initiated a process Instance is somewhat different.
You can perform one out of the following :
Add a private variable and assign it tw.system.user_loginName at the POST of start. you can access that variable for user who initiated the process.(It will be null or undefined for the scenario if task is initiated by some REST API or UCA.)
Place a Tracking group after Start event . Add a input variable to it as username , assign it a value same as tw.system.user_loginName. So whenever Process is started entry will be inserted to DB Table.You can retrieve this value from that view in PerformanceDB.
Also there might be some table ,logging the process Instances details , where you can find the user_id directly.
I suggest you to look in getStarter() method of ProcessInstanceData API.
Official Documentation on API
This link on IBM Developerworks should help you too: Process Starter
Unfortunately there's not an Out Of The Box way to do this - nothing is recorded in the Process Instance that indicates "who" started a process. I presume this is because there are many ways to launch a process instance - from the Portal, via a Message Event, from an API call, etc.
Perhaps the best way to handle this is to add a required Input parameter to your BPD, and supply "who" started the process when you launch it. Unfortunately you can't supply any inputs from the OOTB Portal "New", but you can easilty build your own "launcher".
If you want to route the first task in process to the user that started the process the easiest approach is to simply put the start point in the lane, and on the activity select routing to "Last User In Lane". This will take care of the use case for you without requiring that you do the book keeping to track the user.
Its been a while since I've implemented this, so I can't remember if it will work elegantly if you have system steps before the first task, but this can easily be handled by moving the system steps into the human service to be executed as part of that call, rather than as a separate step in the BPD.
Define variable as string type and using script task to define the login user that use this task and assign it to your defined variable to keep to you in all of the process as initiator of the task.
You can use this line of code to achieve the same:
tw.system.user_loginName
Within my BizTalk 2010 solution I have the following orchestration that’s is started by the receipt of a courier update message. It them makes a couple of call to AX's WCF AIF via two solicit-response ports, a Find request and an Update request.
For this application we are meeting audit requirements through use of the tracking database to store the message body. We are able to link to this from references provided in BAM when we use the TPE. The result for the customer is nice, they get a web portal from which they can view BAM data of message timings etc. but they can also click a link to pull up a copy of the message payloads from the tracking db. Although this works well and makes use of out-of-box functionality for payload storage it has led to relatively complex jobs for the archiving of the tracking db (but that's another story!).
My problem relates to continuation. I have created the following Tracking Profile:
I have associated the first of the orchestration's two solicit response ports with the continuation RcvToOdx based on the interchange Id and this works, I get the following single record written to the Completed activity table:
So, in this case we can assume that an entry was first written on receipt in the inbound message, with the TimeReceivedIntoBts column populated by the physical file receive port. The FindRequestToAx column was then populated by the physical WCF send port. Because this was bound to the RcvToOdx continuation Id and used the same interchange Id and the previously mentioned file receive message, the update was made to the same activity. Notification of the resulting response was also updated to the same activity record - into the FindResponseFromAx column.
My problem is that I would also like BAM to record a timestamp for the subsequent UpdateRequestToAx. Because this request will have the same interchange Id as the previous messages I would expect to be able to solve this problem by simply binding the AxUpdate send port (both send and receive parts of it) to the same continuation id, as seen in the following screen grab:
I also map the UpdateRequestToAx milestone to the physical Ax_TrackAndTraceUpdate_SendPort (Send) and the OrchestrationCompleted milestone to Ax_TrackAndTraceUpdate_SendPort (Receive)
Unfortunately, when I try this I get the following result:
Two problems can be seen from the above db screen grab:
1. Date for the update send port was inserted into a new activity record
2. The record was never completed
I was surprised by this because I'd thought since they update port was enlisted to use the same continuation, and the single InterchangeId was being used by all ports for the continuation Id then all the data milestones would be applied to a single activity.
In looking for a solution to this problem I came across the following post on Stack Overflow suggesting that the continuation must be closed from the BAM API: BAM Continuation issue with TPE. So, I tried this by calling the following method from an expression shape in my orchestration:
public static void EndBAMContinuation(string continuationId)
{
OrchestrationEventStream.EndActivity(CARRIER_ORDER_ACTIVITY_NAME, continuationId);
}
I can be sure the method was called ok because I wrapped the call with a log entry from the CAT framework which I could see in debug view:
I checked the RcvToOdx{867… continuation Id against the non-closed activity and confirmed they matched:
This would suggest that perhaps the request to end the continuation is being processed before the milestone of the received message from the UpdateAx call?
When I query the Relationsips tables I get the following results:
Could anyone please advise why the UpdateToAx activity is not being completed?
I realise that I may be able to solve the problem using only the BAM API but I really want to exhaust any possibility of the TPE being fit for purpose first since the TPE is widely used in other BizTalk solutions of the organisation.
To solve this problem I created a 2nd continuation in the TPE.
"RcvToOdx" continuation for the Find and "OdxToUpdate" continuation for the update - source is InterchangeId on the initial receive port - UPS_TrackAndTrace (same as for other "RcvToOdx" continuation), dest Id is the InterchangeId mapped to update send port.
