How does one run tests?

The README says

The tests here are run automatically when you type './espruino test'. Ideally their name would represent what they tested, but this hasn't been done yet.

Yet there is no espruino executable file. Is there a way to run all the tests?

Ahh. You have to compile your own. On Linux it's quite easy.

And the readme needs updating, you use --test now.

The only make targets in the Makefile are:

clean
gdb
serialflash
flash
proj

Tried each with BOARDNAME=1 RELEASE=1 ESPRUINO_1V3=1 make <target>, but no espruino script, only the binaries, so the compiler works.

Tried with LINUX=1 make, and it outputs a lot of warnings and this error

libs/graphics/lcd_sdl.c:18:21: fatal error: SDL/SDL.h: No such file or directory
# include <SDL/SDL.h>
                     ^

Tried with BOARDNAME=1 RELEASE=1 ESPRUINO_1V3=1 LINUX=1 make, and it exits with this error:

src/jsutils.c:21:19: fatal error: mconf.h: No such file or directory
 # include "mconf.h"
                   ^

Tried with LINUX=1 make -i (ignore errors), to no avail. Cleaned every time before new run.

Any hints? :)

Just try make (no target needed for Linux), but open the Make file and remove the line that's USE_SDL=1 or similar. I thought that was disabled but maybe somehow I committed it by mistake.

Indeed the USE_LCD_SDL=1 was the problem. Thanks.
