这是我的测试设置代码
const knex = require('../db').knex
beforeEach(() => knex.migrate.rollback()
.then(() => knex.migrate.latest())
.then(() => knex.seed.run())
)
afterEach(() => knex.migrate.rollback()
.then(() => {})
)
出现以下错误
Knex:warning - Can't take lock to run migrations: Migration table is already locked
Knex:warning - If you are sure migrations are not running you can release the lock manually by deleting all the rows from migrations lock table: knex_migrations_lock
Unhandled rejection MigrationLocked: Migration table is already locked
1) "before each" hook for "is not allowed"
Knex:warning - Can't take lock to run migrations: Migration table is already locked
Knex:warning - If you are sure migrations are not running you can release the lock manually by deleting all the rows from migrations lock table: knex_migrations_lock
2) "after each" hook for "is not allowed"
这里是db.js
const Knex = require('knex')
const Bookshelf = require('bookshelf')
const config = require('config')
var bookshelf = null
var knex = null
exports.init = () => {
knex = Knex(config.get('database'))
if (process.env.NODE_ENV !== 'test') {
knex.migrate.latest()
}
bookshelf = Bookshelf(knex)
bookshelf.plugin('registry')
bookshelf.plugin('pagination')
bookshelf.plugin('bookshelf-camelcase')
bookshelf.plugin('visibility')
exports.bookshelf = bookshelf
exports.knex = knex
}
mocha.opts
--ui bdd
--slow 70
--growl
--recursive
--reporter spec
最佳答案
事实证明,由于 mysql,beforeEach
钩子(Hook)花费了很长时间。
使用 this.timeout
为我解决了这个问题!
beforeEach(async function () {
this.timeout(60 * 1000)
await knex.migrate.rollback()
await knex.migrate.latest()
return knex.seed.run()
})
关于javascript - 每次失败之前Mocha mysql knex : Can't take lock to run migrations,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/48213015/
