Add test for native addon making use of zlib #7535
Description
Just like #6274 we need a test for zlib usage. The node.exe binary on Windows does not export zlib symbols and this can be fixed by linking against a .def file with these symbols added.
A basic test could be something like this:
#include <zlib.h>
#include <cassert>
int main() {
z_stream zStream = {};
int err = deflateInit2(&zStream, Z_DEFAULT_COMPRESSION, Z_DEFLATED, -15, MAX_MEM_LEVEL, Z_DEFAULT_STRATEGY);
assert(Z_OK == err);
unsigned char helloString[] = "hello";
unsigned char expectedDeflation[] = {0xca, 0x48, 0xcd, 0xc9, 0xc9, 0x7, 0x0, 0x0, 0x0, 0xff, 0xff};
unsigned char outputString[512];
zStream.avail_in = sizeof(helloString) - 1;
zStream.next_in = (unsigned char *) helloString;
zStream.avail_out = sizeof(outputString);
zStream.next_out = outputString;
err = deflate(&zStream, Z_SYNC_FLUSH);
assert(err == Z_OK || err == Z_STREAM_END);
int deflatedLength = sizeof(outputString) - zStream.avail_out;
for (int i = 0; i < deflatedLength; i++) {
assert(outputString[i] == expectedDeflation[i]);
}
deflateEnd(&zStream);
}
