test: add integration test for MCP server (#1633) This PR introduces a single integration test for `cargo mcp`, though it also introduces a number of reusable components so that it should be easier to introduce more integration tests going forward. The new test is introduced in `codex-rs/mcp-server/tests/elicitation.rs` and the reusable pieces are in `codex-rs/mcp-server/tests/common`. The test itself verifies new functionality around elicitations introduced in https://github.com/openai/codex/pull/1623 (and the fix introduced in https://github.com/openai/codex/pull/1629) by doing the following: - starts a mock model provider with canned responses for `/v1/chat/completions` - starts the MCP server with a `config.toml` to use that model provider (and `approval_policy = "untrusted"`) - sends the `codex` tool call which causes the mock model provider to request a shell call for `git init` - the MCP server sends an elicitation to the client to approve the request - the client replies to the elicitation with `"approved"` - the MCP server runs the command and re-samples the model, getting a `"finish_reason": "stop"` - in turn, the MCP server sends the final response to the original `codex` tool call - verifies that `git init` ran as expected To test: ``` cargo test shell_command_approval_triggers_elicitation ``` In writing this test, I discovered that `ExecApprovalResponse` does not conform to `ElicitResult`, so I added a TODO to fix that, since I think that should be updated in a separate PR. As it stands, this PR does not update any business logic, though it does make a number of members of the `mcp-server` crate `pub` so they can be used in the test. One additional learning from this PR is that `std::process::Command::cargo_bin()` from the `assert_cmd` trait is only available for `std::process::Command`, but we really want to use `tokio::process::Command` so that everything is async and we can leverage utilities like `tokio::time::timeout()`. The trick I came up with was to use `cargo_bin()` to locate the program, and then to use `std::process::Command::get_program()` when constructing the `tokio::process::Command`. 2025-07-21 10:27:07 -07:00			`mod mcp_process;`
