"bun test" hangs up in timeout with PostgreSQL and expect->toThrow() #19130
Description
What version of Bun is running?
1.2.10
What platform is your computer?
Microsoft Windows NT 10.0.26100.0, x64
What steps can reproduce the bug?
Unit test with "Bun test" are handing up when "Test 3" is active with expect(async () => {}).toThrow();.
If I drop "Test 3" everything is running.
Also if I replace the inner function with something that is not working with the DB it will work.
But with a database function inside it will run into timeout and will never close.
It hangs up and I need to kill the process from console.
I wrote a simple test to reproduce:
import { describe, test, expect, beforeAll, afterAll } from "bun:test";
import { getDbSchema, users, type DatabaseSchema } from "../../db/db-schema";
import { BunSQLDatabase, drizzle } from "drizzle-orm/bun-sql";
import { SQL } from "bun";
/**
* DB connection
*/
let dbClient = new SQL(
`postgresql://${process.env.POSTGRES_USER}:${process.env.POSTGRES_PASSWORD}@${process.env.POSTGRES_HOST}:${process.env.POSTGRES_PORT}/${process.env.POSTGRES_DB}`
);
let drizzleClient: BunSQLDatabase<DatabaseSchema>;
const connectToDb = async () => {
const schema = getDbSchema();
drizzleClient = drizzle(dbClient, { schema, logger: false });
return drizzleClient;
};
const cleanUpAllData = async () => {
// do something with the db
await drizzleClient.select().from(users);
};
/**
* Mock functions
*/
const addSomeData = async () => {
// do something with the db
const r = await drizzleClient.select().from(users);
return {
id: r[0].id,
};
};
const doSomething = async (id: string) => {
// do something with the db
const r = await drizzleClient.select().from(users);
return r[0].id === id;
};
const doSomethingElse = async () => {
// do something with the db
const r = await drizzleClient.select().from(users);
throw new Error("This fails");
};
describe("getKnowledgeEntries Permissions", () => {
let addedData: { id: string };
beforeAll(async () => {
await connectToDb();
addedData = await addSomeData();
});
afterAll(async () => {
await cleanUpAllData();
});
test("Test 1", async () => {
const result = await doSomething(addedData.id);
expect(result).toBe(true);
});
test("Test 2", async () => {
expect(async () => {
await doSomethingElse();
}).toThrow();
});
test("Test 3", async () => {
const result = await doSomething(addedData.id);
expect(result).toBe(true);
expect(async () => {
await doSomethingElse();
}).toThrow();
});
});What is the expected behavior?
Run the test and close application after that
What do you see instead?
Hanging up and tests are not resolving.
