I have the following documents in my collection
[
{job : "(smoke) test-online", build : 1, status: 1, test: "test-search"},
{job : "(smoke) test-online", build : 1, status: 1, test: "test-create"},
{job : "(smoke) test-online", build : 2, status: 1, test: "test-search"},
{job : "(smoke) test-online", build : 3, status: 1, test: "test-create"},
{job : "(smoke) test-inside", build : 3, status: 1, test: "test-create"}
]
I want to get statistics for all the latest build projects: the number of tests with the status 1, 2, 3, 4.
But I could only get a number of tests in the latest build assemblies.
db.getCollection('test_results').aggregate(
[
{$match: {job: {$regex: 'test-online'}}},
{$group: {_id: {job: "$job", build: "$build"}, lastBuild: {"$last": "$build"}, count: {$sum: 1}}}
]
)
How to find a certain status?
{
"result" : [
{
"_id" : {
"job" : "(smoke) test-online",
"build" : 10
},
"lastBuild" : 10,
"count" : 48.0000000000000000,
"count_success": 12, //status 1
"count_fail": 12, //status 2
"count_skip": 12, //status 4
"count_error": 12 //status 3
},
{
"_id" : {
"job" : "(smoke) test-inside",
"build" : 272
},
"lastBuild" : 272,
"count" : 60.0000000000000000,
"count_success": 260,
"count_fail": 6,
"count_skip": 6,
"count_error": 0,
}
]
Try the following aggregation pipeline:
db.test_results.aggregate([
{
"$match": {
"job": {"$regex": 'test-online'},
"status": {"$in": [1,2,3,4]}
}
},
{
"$group": {
"_id": {
"job": "$job",
"build": "$build"
},
"lastBuild": {
"$last": "$build"
},
"count": {"$sum": 1},
"count_success": {
"$sum": {
"$cond": [
{ "$eq": ["$status", 1] },
1,
0
]
}
},
"count_fail": {
"$sum": {
"$cond": [
{ "$eq": ["$status", 2] },
1,
0
]
}
},
"count_skip": {
"$sum": {
"$cond": [
{ "$eq": ["$status", 4] },
1,
0
]
}
},
"count_error": {
"$sum": {
"$cond": [
{ "$eq": ["$status", 3] },
1,
0
]
}
}
}
}
])
Output (with the above example):
/* 0 */
{
"result" : [
{
"_id" : {
"job" : "(smoke) test-online",
"build" : 3
},
"lastBuild" : 3,
"count" : 1,
"count_success" : 1,
"count_fail" : 0,
"count_skip" : 0,
"count_error" : 0
},
{
"_id" : {
"job" : "(smoke) test-online",
"build" : 2
},
"lastBuild" : 2,
"count" : 1,
"count_success" : 1,
"count_fail" : 0,
"count_skip" : 0,
"count_error" : 0
},
{
"_id" : {
"job" : "(smoke) test-online",
"build" : 1
},
"lastBuild" : 1,
"count" : 2,
"count_success" : 2,
"count_fail" : 0,
"count_skip" : 0,
"count_error" : 0
}
],
"ok" : 1
}
