Testing

Stellar Explorer uses Vitest with the happy-dom environment.

Running Tests

bun run test           # Run all tests once
bun run test:watch     # Run in watch mode

Run a single test file:

bunx vitest run src/lib/utils/format.test.ts

Test File Location

Test files live alongside their source files using the *.test.{ts,tsx} naming convention:

src/lib/utils/
  format.ts
  format.test.ts

Writing Tests

import { describe, it, expect } from "vitest";
import { formatAmount } from "./format";

describe("formatAmount", () => {
  it("formats XLM amounts correctly", () => {
    expect(formatAmount("10000000")).toBe("1.0000000");
  });
});

Environment

Tests run in happy-dom, a lightweight browser environment. This allows testing React components without a full browser.
