航天相机中的TDI CCD成像单元是相机电子学系统中的关键单元，其测试内容多、覆盖性要求全面。对TDI CCD相机的测试往往采用人在回路的手段，测试人员操作测试软件对被测设备发送指令并判读遥测。人在回路测试方法的优点是测试过程比较灵活，可以针对测试过程中出现的问题及时作出响应。但其缺点是测试时间长，测试覆盖性差且容易引入人为错误。为避免人在回路测试方法不足，本文设计了一种无人值守快速测试管理软件，对测试项目进行合理规划，通过测试程序自主完成所有测试，最终形成测试报告。本软件对成像单元的测试覆盖率达到100%，测试时间较传统测试方法缩短50%。

TDI CCD imaging unit is the key element in aerospace camera electronics system, and it has a lot of test content and more comprehensive coverage requirements. TDI CCD imaging unit test is often adopted the method of people in the loop. The tester operates test software on the device under test to send instructions and interpret telemetry data. The method of people in the loop has the advantage of more flexible test process and be able to target the problem in the testing process to respond in a timely manner. But the disadvantage is the long test time, test coverage is poor and easy introduction of human error. In order to avoid shortage of people in the loop test method, this paper designs an unattended quick test software. The test software makes a reasonable planning, independently completes all testing process independently and forms a test report eventually. The test coverage of the imaging unit reached 100%, the test time compared to traditional testing method is shortened by 50%.
