Bare Test

A test framework for testing the bare metal.

Usage

1. Install ostool.

   cargo install ostool
   

2. setup .cargo/config.toml

   [target.'cfg(all(target_os = "none"))']
   runner = "ostool cargo-test"
   [build]
   target = "aarch64-unknown-none"
   

3. setup cargo.toml.

   [dev-dependencies]
   bare-test = "0.0.1"
   
   [build-dependencies]
   sparreal-macros = "0.0.1"
   

4. setup build.rs.

   fn main() {
       sparreal_macros::build_test_setup!();
   }
   

5. new tests dir and add tests.rs.

   #![no_std]
   #![no_main]
   #![feature(custom_test_frameworks)]
   #![test_runner(bare_test::test_runner)]
   #![reexport_test_harness_main = "test_main"]
   
   extern crate bare_test;
   
   #[bare_test::entry]
   fn main() {
       test_main();
   }
   
   use bare_test::println;
   #[test_case]
   fn it_not_works() {
       println!("test2... ");
       assert_eq!(1, 2);
   }
   #[test_case]
   fn it_works1() {
       println!("test1... ");
       assert_eq!(1, 1);
   }
   #[test_case]
   fn test_uart(){
       // map uart data register for using.
       let uart_data_reg = iomap(0x9000000.into(), 0x1000);
   
       // write to uart, then it will be print to the screen.
       unsafe{
           uart_data_reg.write_volatile(b'A');
           uart_data_reg.write_volatile(b'\n');
       }
   
       println!("uart test passed!");
   }
   

6. run cargo test --test tests -- --show-output.
