[ANN] Historia - an event sourcing framework for Pharo
by Masashi UMEZAWA April 29, 2025

April 29, 2025

Hi all, I'm pleased to announce Historia - an event sourcing framework for Pharo. https://github.com/mumez/Historia Historia provides a straightforward way to model your application's state changes as a sequence of immutable events. Key features include: - Model object mutations recorded as timestamped events - ModelSpace (aggregation) for managing named model objects - Automatic synchronization of remote ModelSpaces - Time travel capability to restore state at any point in history - Reliable persistent storage (Redis) for snapshots and events - Inter-ModelSpace communication via EventBridge - Included Bank Account example demonstrating framework usage The framework is designed to be lightweight yet useful for implementing event driven style apps in Pharo. Enjoy! -- [:masashi | ^umezawa]

The goal of the workshop is to create a forum around contributions and experiences in building or using technologies related to Smalltalk. While the maturity of presented ideas and results is not crucial, their presentation is expected to trigger discussion and exchange of ideas. The topics of your paper can be on all aspects of Smalltalk, theoretical as well as practical.

We also invite authors of contributions related to IWST's topics, accepted for publication in Journals and Proceedings of top-rated international conferences within the previous 2 years, to submit an abstract and present their published results to the IWST workshop collocated with ESUG. Authors will be invited to present their paper after checking that the submission meets the above criteria.

Re: [Pharo-users] "Introducing Hera: Gherkin-style tests" â New blog post on all: objects all: theTime
by Koen De Hondt March 28, 2025

March 28, 2025

Hi Guille, > I wonder, are there any good practices/recommendations regarding how to share state between steps? I think there is basically no difference with a unit test. As I wrote in https://all-objects-all-the-time.st/#/blog/posts/10, under "Shared setup and teardownâ, there are a few different ways to cope with different state required by different tests on the same class. My advice would be to create a new class if tests require different state. So I would answer yes to your question "Should this scenario be in a separate feature (shared state?), and all states related to this be in the shared state?â While shared state may be confusing in a unit test, in Hera, and also in Cucumber for Ruby, people can use traits (or Ruby modules) to group steps that use the same state. That way, the different states required by different scenarios can be nicely separated. Even if there are no traits, like in VisualWorks, helper classes can be used to group steps, and instances of those helper classes can carry state. > What kind of heuristics do people use to say things like: > - ok, these two things will be two scenarios of the same feature > - and here, these two need to be in separate features That is a good question. Given that a feature contains different scenarios, people would typically group all scenarios together. But that is not required. You can have different features files in Cucumber that describe different aspects of the same feature (the âFeature:â line at the top would have the same name). In Hera, it would result in different feature methods on different classes. Splitting up a feature is also a way to keep the tests maintainable. > I imagine that a âpuristâ (:D) would try to make features more business-oriented. > But I cannot stop thinking that some âease of implementationâ can creep inside if they simplify the test writing. Yes, features are business-oriented, as they are used to describe acceptance criteria (that is why Heraâs test class is called HeraAcceptanceTest). I guess that with "ease of implementationâ you mean that people are tempted to write imperative-style steps, rather than declarative-style steps. For instance, one can write imperative-style steps like this: Given I am on the sign-in page When I enter my email address in the email field And I enter my password in the password field And I press the âSign inâ button Then I see the home page while a declarative style would result in: Given I am signed in where the latter makes abstraction of how signing in should be done. Letâs discuss more at the Pharo Sprint today. Thank you for the support and the good feedback.
