foundation-test-support

Test support utilities for rust-framework-workspace - live-Postgres harness via env-var connection (Docker retired, sprint 0.38)

What it is for

Test support utilities for rust-framework-workspace.

Provides a Testcontainers-based PostgreSQL harness that:

• Spins up a fresh Postgres container per test suite
• Applies all migrations in the correct dependency order
• Exposes a connection pool for tests
• Cleans up automatically when dropped

# Usage

use foundation_test_support::TestDb;

#tokio::test
async fn test_something() {
let db = TestDb::new().await.expect("Failed to start test database");
let pool = db.pool();

// Your test code here using pool
}

# Migration Order

Migrations are applied in a strict topological order based on dependencies: 1. Foundation layer (basemodels first) 2. Identity layer (parties, then auth, rbac, identifiers) 3. Domain layer (encounters, catalog, billing, etc.) 4. Content layer (documents, notes, cms) 5. Infrastructure layer (communication)

# CI Considerations

• Container reuse is disabled for determinism
• Postgres 16 is used (pinned version)
• Timeouts are set for container startup (60s) and migrations (120s)

Capabilities

No public items.

How to use it

From this crate's own rustdoc:

use foundation_test_support::TestDb;

#[tokio::test]
async fn test_something() {
    let db = TestDb::new().await.expect("Failed to start test database");
    let pool = db.pool();

    // Your test code here using pool
}

Module structure

No public modules: the crate root is its whole surface.

Public surface

No public items.

Re-exports. Exported here, defined elsewhere.

Boundary

Depends on no other workspace tier.

Shares tier foundation with 27 other crates: foundation-audit-log, foundation-basemodels, foundation-bounded-io, foundation-conversation-closure, foundation-crypto-sign, foundation-decisioning, foundation-encounter-vocabulary, foundation-fs-metadata, … (27 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

Related capabilities

3 workspace crates depend on this one: tools-corpus, tools-session-error-audit, tools-untracked-intake.
