:tada: Today, we are excited to announce the official release of a new version of the Rust - and Python -PocketIC testing library alongside a new version of the PocketIC-Server. :tada: PocketIC is a canister testing platform that supports deterministic, programmatic canister testing. It is lightweigh…

Hi @ilbert , regarding the API specification: we’ve tried to document all public functions of the Rust and Python libraries with docstrings. As for the REST API of the PocketIC server, we do not have a specification at the moment, but we are looking into adding one, as this has been requested by othe…

[image] dsd: let pic = PocketIc::new(); Just a quick question regarding this instantiation, does this spin up isolated execution environments/sandboxes for the separate integration tests that we run or are all of the canisters created running in the same execution environment and they share t…

Hi @saikatdas0790 , what you’ve said is exactly right. This line does the following: It starts a PocketIC server if it’s not already running, otherwise the server is reused. Then, a fresh and independent instance (think StateMachine) is created, which you can use in your test. You can then install …

It is pretty fast. Also when I try to push dfx (artificial delay 0) and populate the backend. I am getting Server returned an error: Code: 429 (Too Many Requests) Body: The service is overloaded. While pocket-ic doesn’t complain. Is it possible to add some of these optimisations to dfx, like df…

Hi infu, good to hear. We think that is possible, and we are exploring adding the IC’s HTTP layer to PocketIc, which would make the agent libraries compatible and enable frontends. But this is currently in an early exploration stage and we cannot promise anything at this time. If you have any othe…

@michael-weigelt I would like to report a couple of issues we are encountering with PocketIC. Firstly, in version 2.1.0 of PocketIC, the default features of reqwest are not properly set to false. Consequently, both native-tls and rustls are enabled by default. This issue is causing complications in…

Hi ufoscout Thank you for the feedback, we will look into it. Is your first point a regression with regards to a previous version?

Hi @ufoscout , we’ve updated the PocketIC Rust crate to not use default features again, it will be released with the next release. Regarding the inspect_message check, could you please provide some more details where the panic is happening and where you’d expect an error? Maybe with a short code snip…
