It covers happy-path, negative, boundary and edge-case, authentication and authorization, and contract and schema validation tests using the browser-based "Try it out" feature. ### Source excerpt With the last post, Testing the Swagger Petstore: Reviewing API Documentation Formatted in OpenAPI 3.0 with Swagger UI we started exploring an API with Swagger UI, such as the Swagger Petstore at https://petstore3.swagger.io/ Here, we will start exploring how to test an API using the Swagger UI. The tests we can run are: Happy Path Testing, checking the Positive Scenarios Negative Testing, reviewing the Invalid Inputs & Error Handling Boundary & Edge Case Testing, checking how the API handles the extreme limits of allowed input ranges Authentication & Authorization Testing Contract and schema validation We can see in the Swagger PetStore there are three tag groups: Pet, Store, and User. Because this is a Swagger UI doc, we can perform manual testing using only the "Try it out" feature in Swagger UI. No external tools needed! Live HTTP requests can be executed directly from your browser. Types of Testing for the API Here are a few types of testing and examples you can do in Swagger UI Happy path Functional Testing Pet POST /pet: add a new pet with a complete, valid payload. Verify 200 and that the response echoes the submitted fields. PUT /pet: update the pet you just created. Verify the change persists on a follow-up GET. GET /pet/{petId}: retrieve the pet by the ID returned from the POST. GET /pet/findByStatus: query with each valid status value (available, pending, sold) individually. GET /pet/findByTags: query with a tag that exists on a pet you created. POST /pet/{petId} (form data): update name/status via form fields instead of JSON body. POST /pet/{petId}/uploadImage: upload a valid image file, verify response message and metadata. DELETE /pet/{petId}: delete a pet you created, then confirm GET on that ID now fails. Store POST /store/order: place an order with valid petId, quantity, shipDate, status. GET /store/order/{orderId}: retrieve the order just placed. GET /store/inventory: verify it returns a status-to-count map without needing auth.

It also describes limitations caused by representation changes, abstraction boundaries, mutability, and generic virtual calls. ### Source excerpt Declaring a value class is first and foremost a semantic decision. It tells our fellow programmers that its instances are defined entirely by their state and do not need identity. That clearer model is valuable in itself! The JVM's additional freedom to optimize how those values are represented is a welcome bonus. C2 can do amazing things with that freedom, but it cannot always recover information hidden behind abstraction boundaries. Profiling and inspecting the generated code remain the best ways to understand what is happening. To get the best results, we may still need to have a little sympathy for the compiler. ## Supply chain attack on arrayref DevFeed: [Supply chain attack on arrayref]() Original publisher: [Read original article]() Author: Manish Goregaokar Published: 2026-08-20T00:00:00Z Content type: news Language: en Sources: [Rust Blog]() Topics: [Rust](), [Security]() Tags: [local](), [payload](), [research](), [rust](), [security](), [supply-chain]() ### AI overview The Rust Security Response Team confirmed a supply-chain attack involving malicious crates. A compromised build script downloaded a malicious payload, leading to the deletion or yanking of affected versions and the locking of a potentially compromised account. Developers are advised to inspect their local Cargo registry cache for the listed crates and versions. ### Source excerpt What happened On 2026-08-20 at 7:15 UTC we got a report that the proc-macro1 crate was malicious. The Rust Security Response Team verified this to be the case: the crate had a build script that was downloading a malicious payload. This crate proc-macro1 and others like it (proc-macro-en, aovine, arone, aronenao, tinymember) have been deleted. Furthermore, we discovered that the popular arrayref crate had recently been republished and made to depend on this crate, with the most recent versions yanked. We have removed the malicious version and unyanked the maliciously-yanked versions. Other crates by that author (internment, append-only-vec) were also affected so we have done the same for those, and locked the account as a precaution. We do not believe the author of arrayref to be acting maliciously, but their computer or credentials are likely compromised, and we are attempting to contact them. What you need to do We recommend you check your local dependencies to ensure these crates were not pulled in. Here are the malicious versions that we deleted from crates.io: append-only-vec@0.1.9: published at 2026-08-20T07:37:49Z, deleted at 2026-08-20T09:25:24Z.

It provides verified visitor identity to application code, supports group-based authorization, enables token verification in downstream services, and records successful authentications in activity and audit logs. ### Source excerpt Vercel Passport is now generally available. Passport allows you to protect your Vercel deployments with your own identity provider. Visitors authenticate through Okta, Microsoft Entra ID, or any OIDC provider before viewing a protected deployment, and Vercel forwards a signed identity token to the deployment so application code can build on who the visitor is. Read visitor identity in application code The getIdentity() helper in @vercel/passport reads the Vercel request context and returns the authenticated visitor. Vercel strips client-supplied values for the x-vercel-oidc-passport-token header and injects the verified token after Passport validates the session, so the identity your code receives is already verified. The subject field is a stable identifier for the visitor, scoped to your team and the Vercel Connect application that links Passport to your identity provider, and externalSubject is the visitor's ID in the provider itself. The helper returns null only when a request arrives without a Passport session, because unauthenticated browser visitors are redirected to the identity provider before they ever reach your code. In local development, getIdentity() returns a configurable development identity, so the same code path works without a real identity provider. Authorize with groups from your identity provider The signed Passport token can now carry additional identity claims from your provider, such as group membership. Request the groups scope and allowlist the claim in the Vercel Connect application that Passport uses, then read it from the identity payload: The additional identity scopes documentation covers provider configuration, including a full Okta walkthrough. Verify identity in downstream services Forward the Passport token from your application to another backend as a bearer token and verify it there with verifyIdentity(), available in @vercel/passport 1.0.0 and later. The helper checks the token signature, the Passport claims, and that the token ## Introducing the J2sw MTU and Encapsulation Calculator DevFeed: [Introducing the J2sw MTU and Encapsulation Calculator]() Original publisher: [Read original article]() Author: j2sw Published: 2026-07-28T16:37:53Z Content type: tutorial Language: en Sources: [Justin Wilson (j2sw)]() Topics: [Network](), [Tool](), [Ethernet](), [VXLAN]() Tags: [calculator](), [cisco](), [ethernet](), [fragmentation](), [gre](), [headers](), [ipsec](), [ipv4](), [ipv6](), [juniper](), [mikrotik](), [mpls](), [mtu](), [network-engineering-resources](), [network-tools](), [network-troubleshooting](), [overhead](), [payload](), [pppoe](), [vlan](), [vxlan]() ### AI overview The article introduces the J2SW MTU and Encapsulation Calculator, which estimates inner IP MTU and required underlay MTU for combinations of PPPoE, GRE, VLAN, MPLS, VXLAN, and other encapsulations.
