+# SmartCodable Test
+
+The current SmartCodable unit test process looks like this:
+
+The developer's self-test, the demo provides a variety of exhaustive scenarios, will be verified again.
+SmartCodable is also used in corporate projects, where business teams test at the functional level.
+Each SmartCodable version release will be synchronized to the QQ communication group (group number: 865036731) for online verification.
+A major version update of SmartCodable will be released as a beta version for public testing, which can take anywhere from 2 to 4 weeks depending on the size of the feature.
+
+
+
+目前SmartCodable的单元测试流程是这样的：
+
+1. 开发人员的自测，demo中提供的穷举的各种场景，都会验证一遍。
+2. SmartCodable也用在商业项目中，业务团队会进行功能层面的测试。
+3. SmartCodable每次版本发布都会同步到QQ交流群（群号：865036731）做线上验证。
+4. SmartCodable的大版本更新，会发布beta版本，进行公测，根据功能大小，公测时间2～4周不等。
+
+
+
+
+
+### Build test cases that are as complete as possible
+
+构建尽可能完善的测试用例。
