Chewy, RSpec and Threads raising a weird error












0















I'm testing some concurrent behaviours using RSpec and a weird exception is raised.



expect{

  threads = 4.times.map do

    Thread.new do

      WebMock.allow_net_connect!

      PaymentForm.new(params).process

    end

  end



  threads.each(&:join)

}.to change{

  Payment.count

}.by(1)


After the PaymentForm#process method is called, it creates a Payment (model) record. The Payment model is indexed using Chewy on ElasticSearch, updating the index right after the model is saved.



It turns out that a weird exception is raised:



  1) Checkout::PaymentForm#process when the payment is duplicated blocks repeated transactions

     Failure/Error: unless save



     NoMethodError:

       undefined method `get' for nil:NilClass

From what I could debug, the exception happens when Chewy tried to update the index using Faraday HTTP client.



I'm also using WebMock, but I'm calling WebMock.allow_net_connect! for each thread, making it permissive. Note that this only happens when I use threads. Without threads that runs fine.

      From what I could debug, the exception happens when Chewy tried to update the index using Faraday HTTP client.



      I'm also using WebMock, but I'm calling WebMock.allow_net_connect! for each thread, making it permissive. Note that this only happens when I use threads. Without threads that runs fine.

Like this: login screen Nothing to be log when I run flutter run --verbose, so I logged manually. Every tapping on field, the widget called dispose -> init -> build.

But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
