更新测试用例
UsesTests
Swift
func testUserCanBeSavedWithAPI() throws {
let user = User(name: usersName, username: usersUsername, password: "password")
...
}
func testUsersCanBeRetrievedFromAPI() throws {
...
// 发请求并获得响应
let users = try app.getResponse(to: usersURI, decodeTo: [User.Public].self)
...
}
Models+testable
Swift
...
import Crypto
extension User {
static func create(
name: String = "Luke",
username: String? = nil,
on connection: PostgreSQLConnection) throws -> User {
var createUsername: String
if let suppliedUsername = username {
createUsername = suppliedUsername
} else {
createUsername = UUID().uuidString
}
let password = try BCrypt.hash("password")
let user = User(name: name, username: createUsername, password: password)
return try user.save(on: connection).wait()
}
}
...
修改后重置docker测试数据库：
Bash
$ docker stop postgres-test
$ docker rm postgres-test
$ docker run --name postgres-test -e POSTGRES_DB=vapor-test \
-e POSTGRES_USER=vapor -e POSTGRES_PASSWORD=password \
-p 5433:5432 -d postgres
现在运行测试会产生崩溃，因为对那些需要认证的API的调用会失败:
Application+testable.swift

修改完在后一定要跑完单元测试:
