14 |
15 | ## About
16 |
17 | **EphemeralMongo** is a .NET library that provides a simple way to run temporary and disposable MongoDB servers for integration tests and local debugging, without any dependencies or external tools. It is as simple as:
18 |
19 | ```csharp
20 | using var runner = await MongoRunner.RunAsync();
21 | Console.WriteLine(runner.ConnectionString);
22 | ```
23 |
24 | Use the resulting connection string to access the MongoDB server. It will automatically be stopped and cleaned up when the `runner` is disposed. You can pass options to customize the server, such as the data directory, port, and replica set configuration. More details can be found in the [usage section](#usage).
25 |
26 | List of features and capabilities:
27 |
28 | - Multiple ephemeral and **isolated MongoDB databases** for running tests.
29 | - A quick way to set up a MongoDB database for a local development environment.
30 | - Access to **MongoDB 6**, **7**, and **8**.
31 | - Access to **MongoDB Community** and **Enterprise editions**.
32 | - Support for **single-node replica sets**, enabling transactions and change streams.
33 | - _mongoexport_ and _mongoimport_ tools for [exporting](https://www.mongodb.com/docs/database-tools/mongoexport/) and [importing](https://docs.mongodb.com/database-tools/mongoimport/) collections.
34 | - Support for .NET Standard 2.0, .NET Standard 2.1, .NET 8.0 and later.
35 | - Support for Linux, macOS, and Windows.
36 | - Supports **MongoDB C# driver version 2.x and 3.x**.
37 |
38 | This project follows in the footsteps of [Mongo2Go](https://github.com/Mongo2Go/Mongo2Go) and expands upon its foundation.
39 |
40 | ## Installation
41 |
42 | | Package | Description |
43 | | --- | --- |
44 | | [](https://www.nuget.org/packages/EphemeralMongo/) | Install this package if you use MongoDB C# driver version 3.x. |
45 | | [](https://www.nuget.org/packages/EphemeralMongo.v2/) | Install this package if you use MongoDB C# driver version 2.x. |
46 |
47 | ## Usage
48 |
49 | Use `MongoRunner.RunAsync()` or `MongoRunner.Run()` methods to create a disposable instance that provides access to a **MongoDB connection string**, **import**, and **export tools**. An optional `MongoRunnerOptions` parameter can be provided to customize the MongoDB server.
50 |
51 | ```csharp
52 | // All the following properties are OPTIONAL.
53 | var options = new MongoRunnerOptions
54 | {
55 | // The desired MongoDB version to download and use.
56 | // Possible values are V6, V7 and V8. Default is V8.
57 | Version = MongoVersion.V8,
58 |
59 | // The desired MongoDB edition to download and use.
60 | // Possible values are Community and Enterprise. Default is Community.
61 | Edition = MongoEdition.Community,
62 |
63 | // If true, the MongoDB server will run as a single-node replica set. Default is false.
64 | UseSingleNodeReplicaSet = true,
65 |
66 | // Additional arguments to pass to the MongoDB server. Default is null.
67 | AdditionalArguments = ["--quiet"],
68 |
69 | // The port on which the MongoDB server will listen.
70 | // Default is null, which means a random available port will be assigned.
71 | MongoPort = 27017,
72 |
73 | // The directory where the MongoDB server will store its data.
74 | // Default is null, which means a temporary directory will be created.
75 | DataDirectory = "/path/to/data/",
76 |
77 | // Provide your own MongoDB binaries in this directory.
78 | // Default is null, which means the library will download them automatically.
79 | BinaryDirectory = "/path/to/mongo/bin/",
80 |
81 | // A delegate that receives the MongoDB server's standard output.
82 | StandardOutputLogger = Console.WriteLine,
83 |
84 | // A delegate that receives the MongoDB server's standard error output.
85 | StandardErrorLogger = Console.WriteLine,
86 |
87 | // Timeout for the MongoDB server to start. Default is 30 seconds.
88 | ConnectionTimeout = TimeSpan.FromSeconds(10),
89 |
90 | // Timeout for the replica set to be initialized. Default is 10 seconds.
91 | ReplicaSetSetupTimeout = TimeSpan.FromSeconds(5),
92 |
93 | // The duration for which temporary data directories will be kept.
94 | // Ignored when you provide your own data directory. Default is 12 hours.
95 | DataDirectoryLifetime = TimeSpan.FromDays(1),
96 |
97 | // Override this property to provide your own HTTP transport.
98 | // Useful when behind a proxy or firewall. Default is a shared reusable instance.
99 | Transport = new HttpTransport(new HttpClient()),
100 |
101 | // Delay before checking for a new version of the MongoDB server. Default is 1 day.
102 | NewVersionCheckTimeout = TimeSpan.FromDays(2)
103 | };
104 | ```
105 |
106 | ```csharp
107 | // Disposing the runner will kill the MongoDB process (mongod) and delete the associated data directory
108 | using (await var runner = MongoRunner.RunAsync(options))
109 | {
110 | var database = new MongoClient(runner.ConnectionString).GetDatabase("default");
111 |
112 | // Do something with the database
113 | database.CreateCollection("people");
114 |
115 | // Export a collection to a file. A synchronous version is also available.
116 | await runner.ExportAsync("default", "people", "/path/to/default.json");
117 |
118 | // Import a collection from a file. A synchronous version is also available.
119 | await runner.ImportAsync("default", "people", "/path/to/default.json");
120 | }
121 | ```
122 |
123 | ## How it works
124 |
125 | * At runtime, the MongoDB binaries (`mongod`, `mongoimport`, and `mongoexport`) are downloaded when needed (if not already present) and extracted to your local application data directory.
126 | * Official download links are retrieved from [this JSON file](https://downloads.mongodb.org/current.json) for the server and [this JSON file](https://downloads.mongodb.org/tools/db/release.json) for the tools.
127 | * SHA256 checksums are used to verify the integrity of the downloaded files.
128 | * `MongoRunner.Run` or `MongoRunner.RunAsync` always starts a new `mongod` process with a random available port.
129 | * The resulting connection string will depend on your options (`UseSingleNodeReplicaSet`).
130 | * By default, a unique temporary data directory is used and deleted when the `runner` is disposed.
131 |
132 | ## MongoDB Enterprise and in-memory storage engine
133 |
134 | Make sure you are allowed to use MongoDB Enterprise binaries in your projects. The [official download page](https://www.mongodb.com/try/download/enterprise) states:
135 |
136 | > MongoDB Enterprise Server is also available free of charge for evaluation and development purposes.
137 |
138 | The Enterprise edition provides access to the in-memory storage engine, which is faster and more efficient for tests:
139 |
140 | ```csharp
141 | var options = new MongoRunnerOptions
142 | {
143 | Edition = MongoEdition.Enterprise,
144 | AdditionalArguments = ["--storageEngine", "inMemory"],
145 | };
146 |
147 | using var runner = await MongoRunner.RunAsync(options);
148 | // [...]
149 | ```
150 |
151 | ## Windows Defender Firewall prompt
152 |
153 | On Windows, you might get a **Windows Defender Firewall prompt**.
154 | This is because EphemeralMongo starts the `mongod.exe` process from your local app data directory, and `mongod.exe` tries to open an available port.
155 |
156 | ## Reusing runners across tests
157 |
158 | Avoid calling `MongoRunner.Run` or `MongoRunner.RunAsync` concurrently, as this will create many `mongod` processes and make your operating system slower. Instead, try to use a single instance and reuse it - create as many databases as you need, one per test, for example.
159 |
160 | For this, version 3.0.0 introduces a new *experimental* `PooledMongoRunner` class. Once created, you can rent and return `MongoRunner` instances. Once rented a certain number of times, new instances will be created. This way, `mongod` processes will be reused, but not too often. This will avoid uncontrolled usage of system resources.
161 |
162 | ```csharp
163 | var options = new MongoRunnerOptions
164 | {
165 | Version = MongoVersion.V7,
166 | UseSingleNodeReplicaSet = true
167 | };
168 |
169 | using var pool = new MongoRunnerPool(options);
170 |
171 | var runner1 = await pool.RentAsync();
172 | var runner2 = await pool.RentAsync();
173 |
174 | try
175 | {
176 | // Same connection string, same mongod process
177 | Console.WriteLine(runner1.ConnectionString);
178 | Console.WriteLine(runner2.ConnectionString);
179 | }
180 | finally
181 | {
182 | pool.Return(runner1);
183 | pool.Return(runner2);
184 | }
185 |
186 | // This is a new mongod process
187 | var runner3 = await pool.RentAsync();
188 | ```
189 |
190 | ## Changelog
191 |
192 | ### 3.0.0
193 |
194 | See [this announcement](https://github.com/asimmon/ephemeral-mongo/issues/80).
195 |
196 | ### 2.0.0
197 |
198 | - **Breaking change**: Support for MongoDB 5.0 and 6.0 has been removed, as their [end-of-life](https://www.mongodb.com/legal/support-policy/lifecycles) has passed.
199 | - **Breaking change**: arm64 is now the default target for macOS. The previous target was x64.
200 | - **Breaking change**: The Linux runtime package now uses Ubuntu 22.04's MongoDB binaries instead of the 18.04 ones. OpenSSL 3.0 is now required.
201 | - **Breaking change**: Updated the MongoDB C# driver to 2.28.0, [which now uses strong-named assemblies](https://www.mongodb.com/community/forums/t/net-driver-2-28-0-released/289745).
202 | - Added support for MongoDB 8.0.
203 | - Introduced data directory management to delete old data directories automatically.
204 | - Use direct connection in replica set connection strings.
205 | - Fixed the spelling issue in `MongoRunnerOptions.StandardOutputLogger`.
