(chai 5.1.0 from npm, node 18.14.0, v8 10.2.154.23-node.22) It seems that assert.throws() does not work correctly in vm spawned context. ``` const vm = require('node:vm'); const context = {}; vm.createContext(context); setImmediate(runTest); async function runTest() { context.chai = await import('chai'); context.chai.assert.throws(() => { throw new Error('aaa.bbb'); }, /bbb/); // OK vm.runInContext(code, context); // Failure } const code = ` chai.assert.throws(() => { throw new Error('aaa.bbb'); }, /bbb/); `; ``` Default context assert.throws() work as expected, but vm context assert.throws() asserts where it should pass.
