Problem solving checklist


  • Form a mental model of the process taking place. Write it down in words or draw a diagram. Validate that each step in your model is accurate, not just the one you think is failing.
  • Another way to approach the above point - think of all the things that affect the running code, and work out which are the most likely to have an effect. Don't rule out the unexpected ones though. Think how you could test your understanding of, or rule out a problem with, each of the aspects.
    • your code (and different versions thereof)
    • other libraries (and different versions thereof)
    • application server (and different versions thereof)
    • language interpreter, compiler and/or virtual machine (and different versions thereof)
    • properties files
    • environment variables

No successful verifications exist for the pact content by a provider version with the specified tag.
main ref1, basePact
create branchA refA, basePact+integrationA
create branchB refB, basePact+integrationB
main provider build runs, configured to verify main pacts, and WIP pacts.
basePact (explicit), basePact+integrationA (wip), basePact+integrationB (wip) all verified successfully
basePact+integrationA and basePact+integrationB no longer WIP

Using pact with providers that have their own providers

Eg. A -> B -> C

A more find grained view of this intergration might go:

|------------------A Codebase------------------||------------------B Codebase------------------||--------C Codebase---...
 A UI -> A Controller -> B Service -> B Client -> B API -> B Controller -> CService -> CClient -> C API etc...  
                                           |---A/B pact------------------------?
                                           |---A/B pact------------------------------------?

Moderately dirty hack to order pact versions by date instead of version in the pact broker
View caveats.txt
This will sort based on the date that the consumer application version resource is created.
If the pact for that version is updated, the sorting will not consider the date of the updated content.

Ruby pact libraries
View - rpsec specific stuff, top level, executables - standalone, used by javascript, starts up service, listens, writes pact, verification - matching logic, domain objects - pact specification test, people might want version 3 soonish. - standalone package using travelling ruby - this is the task that builds the packages - the javascript DSL that wraps the ruby or standalone mock server.

DelegatedProperty - flattening model hierarchy - don't expose your model relationships in your form

This allows you do something like:

User =
Address =, :suburb)

class UserForm < Reform::Form

  property :address do
    property :street
