All you need to do is create a Request and pass it to the Hono application to validate the Response. You can then use the useful app.request method.
::: tip For a typed test client see the testing helper. :::
For example, consider an application that provides the following REST API.
app.get('/posts', (c) => {
return c.text('Many posts')
})
app.post('/posts', (c) => {
return c.json(
{
message: 'Created',
},
201,
{
'X-Custom': 'Thank you',
}
)
})
Make a request to GET /posts and test the response.
describe('Example', () => {
test('GET /posts', async () => {
const res = await app.request('/posts')
expect(res.status).toBe(200)
expect(await res.text()).toBe('Many posts')
})
})
To make a request to POST /posts, do the following.
