+#### Generating an JSON Report {#JsonReport}
+
+gUnit can also emit a JSON report as an alternative format to XML. To generate
+the JSON report, set the `GUNIT_OUTPUT` environment variable or the
+`--gunit_output` flag to the string `"json:path_to_output_file"`, which will
+create the file at the given location. You can also just use the string
+`"json"`, in which case the output can be found in the `test_detail.json` file
+in the current directory.
+
+The report format conforms to the following JSON Schema:
+
+```json
+{
+ "$schema": "http://json-schema.org/schema#",
+ "type": "object",
+ "definitions": {
+ "TestCase": {
+ "type": "object",
+ "properties": {
+ "name": { "type": "string" },
+ "tests": { "type": "integer" },
+ "failures": { "type": "integer" },
+ "disabled": { "type": "integer" },
+ "time": { "type": "string" },
+ "testsuite": {
+ "type": "array",
+ "items": {
+ "$ref": "#/definitions/TestInfo"
+ }
+ }
+ }
+ },
+ "TestInfo": {
+ "type": "object",
+ "properties": {
+ "name": { "type": "string" },
+ "status": {
+ "type": "string",
+ "enum": ["RUN", "NOTRUN"]
+ },
+ "time": { "type": "string" },
+ "classname": { "type": "string" },
+ "failures": {
+ "type": "array",
+ "items": {
+ "$ref": "#/definitions/Failure"
+ }
+ }
+ }
+ },
+ "Failure": {
+ "type": "object",
+ "properties": {
+ "failures": { "type": "string" },
+ "type": { "type": "string" }
+ }
+ }
+ },
+ "properties": {
+ "tests": { "type": "integer" },
+ "failures": { "type": "integer" },
+ "disabled": { "type": "integer" },
+ "errors": { "type": "integer" },
+ "timestamp": {
+ "type": "string",
+ "format": "date-time"
+ },
+ "time": { "type": "string" },
+ "name": { "type": "string" },
+ "testsuites": {
+ "type": "array",
+ "items": {
+ "$ref": "#/definitions/TestCase"
+ }
+ }
+ }
+}
+```
+
+The report uses the format that conforms to the following Proto3 using the
+[JSON encoding](https://developers.google.com/protocol-buffers/docs/proto3#json):
+
+```proto
+syntax = "proto3";
+
+package googletest;
+
+import "google/protobuf/timestamp.proto";
+import "google/protobuf/duration.proto";
+
+message UnitTest {
+ int32 tests = 1;
+ int32 failures = 2;
+ int32 disabled = 3;
+ int32 errors = 4;
+ google.protobuf.Timestamp timestamp = 5;
+ google.protobuf.Duration time = 6;
+ string name = 7;
+ repeated TestCase testsuites = 8;
+}
+
+message TestCase {
+ string name = 1;
+ int32 tests = 2;
+ int32 failures = 3;
+ int32 disabled = 4;
+ int32 errors = 5;
+ google.protobuf.Duration time = 6;
+ repeated TestInfo testsuite = 7;
+}
+
+message TestInfo {
+ string name = 1;
+ enum Status {
+ RUN = 0;
+ NOTRUN = 1;
+ }
+ Status status = 2;
+ google.protobuf.Duration time = 3;
+ string classname = 4;
+ message Failure {
+ string failures = 1;
+ string type = 2;
+ }
+ repeated Failure failures = 5;
+}
+```
+
+For instance, the following program
+
+```c++
+TEST(MathTest, Addition) { ... }
+TEST(MathTest, Subtraction) { ... }
+TEST(LogicTest, NonContradiction) { ... }
+```
+
+could generate this report:
+
+```json

+ "failures": 1,
+ "errors": 0,
+ "time": "0.035s",
+ "timestamp": "2011-10-31T18:52:42Z"

+ "tests": 2,
+ "failures": 1,

+ "time": "0.015s",
+ "testsuite": [
