鲁达 自从升级了iOS13之后感觉自己就成了一只小白鼠，什么卡机，闪退输入法不能打字，基本上都是小事了，想着既然已经已经是测试版系统了，那么就把所有的软件都变成测试版吧，说不定测试版的APP已经适配了新的iOS系统呢？
TestFlight是iOS App 测试版发布渠道，大家都戏称为“TF＂，一般来说TestFlight的APP测试有２种，一种内部测试,一种是外部测试，人数限制大约为 25 个内部用户和 10000 个外部测试人员测试。我们讨论的也主要是外部测试，内部测试一般都是开发人员自己使用的，外部测试可以理解为公开测试了，之后才会在苹果商店上架。
TestFlight测试对于开发者和用户来说都是很多好处的。
- １，开发者可以通过用户提交的测试反馈来完善和稳定 App
- ２，测试用户可以尝鲜 App 的新功能，但是有可能出现不稳定、闪退、出错等等问题，也有可能更早的适配新的iOS系统反而更稳定。虽然TestFlight 版本有90 天的使用限制，但是测试确实免费的，而且许多不在国内上市的APP，使用TestFlight之后也能使用。比如汤不热等APP。
那么我们要如何使用 TestFlight 参与 App 测试呢？我们可以查看TestFlight官网。
安装好TestFlight后我们要怎么申请参与 TestFlight 测试呢？一般来说如果开发者需要招募 App 测试，一般会有3个主要渠道
1，他们会在自己的社交渠道或者官网放出招募通知，我们可以关注官方Twitter,公众号，官网，QQ群等。
2，很多APP会直接在软件内提示你获得内测资格，只要你按提示安装测试版就可以了。
3，我们可以直接从TestFlight页面参与测试。
