#### 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
{
"tests": 3,
"failures": 1,
"errors": 0,
"time": "0.035s",
"timestamp": "2011-10-31T18:52:42Z"
"name": "AllTests",
"testsuites": [
{
"name": "MathTest",
"tests": 2,
"failures": 1,
"errors": 0,
"time": "0.015s",
"testsuite": [
{
"name": "Addition",
"status": "RUN",
"time": "0.007s",
"classname": "",
"failures": [
{
"message": "Value of: add(1, 1)\x0A Actual: 3\x0AExpected: 2",
"type": ""
},
{
"message": "Value of: add(1, -1)\x0A Actual: 1\x0AExpected: 0",
"type": ""
}
]
},
{
"name": "Subtraction",
"status": "RUN",
"time": "0.005s",
"classname": ""
}
]
}
{
"name": "LogicTest",
"tests": 1,
"failures": 0,
"errors": 0,
"time": "0.005s",
"testsuite": [
{
"name": "NonContradiction",
"status": "RUN",
"time": "0.005s",
"classname": ""
}
]
}
]
}
```
