Macros @eval在@testset name参数中转义$

我在一个文件中有几个

@testset

s，我想将它们的输出对齐。
起初看起来是这样的：

Test Summary: | Pass  Total
short         |    1      1
Test Summary:         | Pass  Total
test with longer name |    1      1

Test Summary:         | Pass  Total
short                 |    1      1
Test Summary:         | Pass  Total
test with longer name |    1      1

@testset $(testName("some for test \$i")) for i in 9:11
    @test i > 0
end

我希望将

|

对齐，使其如下所示：

Test Summary: | Pass  Total
short         |    1      1
Test Summary:         | Pass  Total
test with longer name |    1      1

Test Summary:         | Pass  Total
short                 |    1      1
Test Summary:         | Pass  Total
test with longer name |    1      1

@testset $(testName("some for test \$i")) for i in 9:11
    @test i > 0
end

我尝试使用

@sprintf

使名称的长度相同，但是

@testset

宏需要一个字符串文本。因此，我使用

@eval

在名称中插入格式化字符串：

testName(name) = @sprintf("%-25s", name)

@eval begin

@testset $(testName("short")) begin
    @test true
end

@testset $(testName("test with longer name")) begin
    @test true
end

end # @eval

这为我提供了简单测试集所需的功能，但在使用

for

循环变量插入到名称中。
如果我添加这样的测试：

Test Summary: | Pass  Total
short         |    1      1
Test Summary:         | Pass  Total
test with longer name |    1      1

Test Summary:         | Pass  Total
short                 |    1      1
Test Summary:         | Pass  Total
test with longer name |    1      1

@testset $(testName("some for test \$i")) for i in 9:11
    @test i > 0
end

输出是

Test Summary:             | Pass  Total
short                     |    1      1
Test Summary:             | Pass  Total
test with longer name     |    1      1
Test Summary:             | Pass  Total
some for test $i          |    1      1
Test Summary:             | Pass  Total
some for test $i          |    1      1
Test Summary:             | Pass  Total
some for test $i          |    1      1

看起来eval宏以某种方式逃逸了

$

，它不再与

@testset

宏一起工作。

为什么它不起作用？我如何强制

$

在名称字符串文本中存在而不被替换？（关于如何对齐结果的建议也受欢迎）。

使用带插值的

字符串作为
@testset
宏的参数：

julia> @testset "$(testName("some for test $i"))" for i in 9:11
           @test i > 0
       end;
Test Summary:             | Pass  Total
some for test 9           |    1      1
Test Summary:             | Pass  Total
some for test 10          |    1      1
Test Summary:             | Pass  Total
some for test 11          |    1      1
