我必须给gnattest什么命令，使其仅考虑src目录中的代码（并忽略所有子项目，例如Ada Drivers Library）？
我读过this question，它说要用'Test_Case'方面标记要测试的每个子程序。如果需要的话，我会走那条路线，但是我希望gnattest的保护自动为新代码添加新的测试用例，以便我不会错过任何内容。
这是我的gpr文件：
with "c:\Domains\ada\Ada_Drivers_Library\boards\MicroBit\microbit_zfp.gpr";
project Demo_Project is
for Runtime ("ada") use Microbit_Zfp'Runtime ("Ada");
for Target use "arm-eabi";
for Main use ("main.adb");
for Languages use ("Ada");
for Source_Dirs use ("src");
for Object_Dir use "obj";
for Create_Missing_Dirs use "True";
package Compiler renames Microbit_Zfp.Compiler;
package Linker is
for Default_Switches ("ada") use Microbit_Zfp.Linker_Switches & ("-Wl,--print-memory-usage", "-Wl,--gc-sections", "-U__gnat_irq_trap");
end Linker;
package Ide is
for Program_Host use ":1234";
for Communication_Protocol use "remote";
for Connection_Tool use "pyocd";
end Ide;
package Prove is
for Proof_Switches ("Ada") use ("-j0");
end Prove;
package Builder is
for Switches ("ada") use ("-j0", "-s");
end Builder;
end Demo_Project;
这是GPS创建的gnattest命令（错误地为ada驱动程序库创建了测试）：
arm-eabi-gnat test -Pdemo_project.gpr --tests-dir=C:\Domains\ada\demo_project\microbit\tests
更新：2019-12-17：
这是我运行建议答案时得到的：
>c:\GNAT\2019\bin\gnattest -Pdemo_project.gpr --tests-dir=tests
Could not locate exec arm-eabi-gnatls
gprconfig: can't find a toolchain for the following configuration:
gprconfig: language 'ada', target 'arm-eabi', runtime 'zfp-cortex-m0'
microbit_zfp.gpr:61:25: warning: libraries are not supported on this platform
object path not found for runtime zfp-cortex-m0
gnattest: initialization failed
更新：2019-12-17（2）：
通过像这样添加“ --test-case-only”标志，并在Battery程序包的单个过程中添加了test_case方面，我取得了一些进展。这是我运行的命令：
arm-eabi-gnat test -dd -PC:\Domains\ada\Demo_Project\microbit\demo_project.gpr --tests-dir=C:\Domains\ada\Demo_Project\tests --test-case-only
Gnattest成功。我可以在项目视图中查看电池包以进行测试。但是，当我尝试从GPS生成并运行它时，会出现以下混乱：
gprbuild --target=arm-eabi -d -PC:\Domains\ada\Demo_Project\microbit\obj\gnattest\harness\test_driver.gpr -XADL_BUILD_CHECKS=Enabled -XADL_BUILD=Debug -XTEST_DRIVER_BUILD_MODE=no-config-file C:\Domains\ada\Demo_Project\microbit\obj\gnattest\harness\test_runner.adb -largs -Wl,-Map=map.txt

存在三个问题：
FYI：我正在Windows 7上运行gnat，ARM交叉编译器和GPS的2019社区版本。
您链接的问题是只测试几个子程序，而不是测试一个项目中的所有源代码，这应该很容易：
gnattest -Pproject.gpr
您可以指定一个或多个特定文件：
gnattest -Pproject.gpr file1.ads file2.ads
只需avoid -r，就可以了：
-r递归考虑所有项目的所有来源
