我正在使用Rails 5.1.13
当我进行个别测试时，它会通过：
rails test test/api/controllers/positions_controller_test.rb
但是当我在一个文件夹中运行所有测试时，它会失败：
rails test test/api/controllers/
出现此错误消息： test_should_get_index已在
中定义Running via Spring preloader in process 14518

当我单独运行时，该文件夹中的所有和每个测试都会通过。
我对控制器的所有测试都或多或少地具有相同的形式，如下所示：
require 'test_helper'
class Api::V1::PositionsControllerTest < ActionDispatch::IntegrationTest
setup do
@school = schools(:school_one)
@teacher = teachers(:teacher_one)
@course = courses(:course_one)
@position = positions(:position_one)
end
test "should get index" do
get api_v1_positions_url
assert_response :success
end
test "should create position" do
assert_difference('Position.count') do
post "/api/v1/positions", params: { position: { course_id: @course.id, shift: "tarde", status: "activo", teacher_id: @teacher.id, position_type: "titular" }}
end
assert_response 201
assert_response :success
end
test "should show position" do
get api_v1_position_url(@position)
assert_response :success
end
test "should update position" do
patch api_v1_position_url(@position), params: { position: { shift: "tarde", status: @position.status, teacher_id: @position.teacher_id, position_type: "suplente" } }
assert_response :success
end
test "should destroy position" do
assert_difference('Position.count', -1) do
delete api_v1_position_url(@position)
end
assert_response :success
end
end
