+# We support too many combinations of Rust releases, crate features, operating
+# systems, and architectures to even remotely test all combinations.
+# Yet it turns out we can test most of these independent of each other, because
+# they serve different goals or test different pieces of code.
+#
+# RUST RELEASES
+# Goal: make sure we don't use language features unavailable on a certain
+# version, and build without warnings.
+# We have different builders use 4 Rust releases, a pinned stable release,
+# the latest stable, beta and nightly.
+#
+# ARCHITECTURES
+# Goal: test against issues caused by differences in endianness, pointer sizes,
+# etc.
+# We run tests on 4 different architectures.
+# - x64_84, default on Travis (Linux) and AppVeyor (Windows)
+# - i686, second AppVeyor (Windows) configuration
+# - MIPS, big-endian Linux emulated with QEMU (thanks to Trust)
+# - ARMv7, Android emulated with QEMU (thanks to Trust)
+#
+# OPERATING SYSTEMS
+# Goal: test on many operating systems, to verify the OsRng code, which is
+# mostly architecture-independent.
+# We run tests on Linux, OS X, Windows, Android (emulated), and Node.js (using
+# cargo-web).
+# One builder cross-compiles for many of the remaining OSes, which ensures we
+# keep building, but doesn't run tests.
+# OSes supported by Rand but which we can't cross-compile because there
+# is no pre-built standard library available: Dragonfly BSD, Haiku, OpenBSD.
+#
+# CRATE FEATURES, TESTS, AND SUB-CRATES
+# Goal: Run unit tests, doctests, examples, and test benchmarks for all crates,
+# in configurations that cover all interesting combinations of features.
+# (`--lib` only runs unit tests just like `--tests`, but the latter is not
+# available in Rust 1.22.0)
+# Tests run on rand:
+# - test no_std support, but only the unit tests:
+# `cargo test --lib --no-default-features`
+# - run unit tests and doctests with all features which are available on stable:
+# `cargo test --features=serde1,log`
+# - test examples:
+# `cargo test --examples`
+# Additional tests on nightly:
+# - run unit tests and doctests with all features which are available on nightly:
+# `cargo test --all-features`
+# - test no_std support, including the nightly alloc feature:
+# cargo test --lib --no-default-features --features=alloc
+# - run benchmarks as tests:
+# `cargo test --benches --features=nightly`
+# Tests on subcrates:
+# - select crates via --manifest-path (more reliable than --package)
+# - test appropriate feature matrix
+#
+# TODO: SIMD support on stable releases
+# NOTE: SIMD support is unreliable on nightly; we track the latest release
