Function toJSONHierarchy

string toJSONHierarchy(T) (
  const(T)[][string] items
);

Example

convert an assoc array to JSON hierarchy 

struct Mock {
  string val;

  string toString() inout {
    return `"` ~ val ~ `"`;
  }
}

const(Mock)[][string] mocks;

mocks["a.b"] = [ Mock("val1"), Mock("val2") ];
mocks["a.c"] = [ Mock("val3") ];

auto result = mocks.toJSONHierarchy;

result.should.contain(`
  "b": [
    "val1",
    "val2"
  ]`);
result.should.contain(`"c": [
    "val3"
  ]`);
result.should.startWith(`{
"a": {`);
result.should.endWith(`
  ]
}
}`);

Example

it should have an empty key for items that contain both values and childs 

struct Mock {
  string val;

  string toString() inout {
    return `"` ~ val ~ `"`;
  }
}

const(Mock)[][string] mocks;

mocks["a.b"] = [ Mock("val1"), Mock("val2") ];
mocks["a.b.c"] = [ Mock("val3") ];

mocks.toJSONHierarchy.should.equal(`{
"a": {
  "b": {
    "c": [
      "val3"
    ],
    "": [
    "val1",
    "val2"
    ]
  }
}
}`);

Example

describeTests should return the tests cases serialised in json format 

void TestMock() @system { }

TestCase[] tests;
tests ~= TestCase("a.b", "some test", &TestMock, [ Label("some label", "label value") ]);
tests ~= TestCase("a.c", "other test", &TestMock);

auto result = describeTests(tests);

result.values.length.should.equal(2);
result.keys.should.containOnly([ "a.b", "a.c" ]);
result["a.b"].length.should.equal(1);
result["a.c"].length.should.equal(1);
