Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
github.com/nbio/st
A tiny test framework for making short, useful assertions in your Go tests.
Assert(t, have, want)
and Refute(t, have, want)
abort a test immediately with t.Fatal
.
Expect(t, have, want)
and Reject(t, have, want)
allow a test to continue, reporting failure at the end with t.Error
.
They print nice error messages, preserving the order of have (actual result) before want (expected result) to minimize confusion.
Examples of passing tests from readme_test.go
:
func TestExample(t *testing.T) {
st.Expect(t, "a", "a")
st.Reject(t, 42, int64(42))
st.Assert(t, "b", "b")
st.Refute(t, 99, int64(99))
}
func TestTableExample(t *testing.T) {
examples := []struct{ a, b string }{
{"first", "first"},
{"second", "second"},
}
// Pass the index to improve the error message for table-based tests.
for i, ex := range examples {
st.Expect(t, ex, ex, i)
st.Reject(t, ex, &ex, i)
}
// Cannot pass index into Assert or Refute, they fail fast.
for _, ex := range examples {
st.Assert(t, ex, ex)
st.Refute(t, ex, &ex)
}
}

--- PASS: TestExample (0.00 seconds)
=== RUN TestTableExample

Failing tests produce nice output:
func TestFailedExpectationMessages(t *testing.T) {
st.Expect(t, 1, 2)
st.Reject(t, "same", "same")
var typedNil *string
st.Expect(t, typedNil, nil) // in Go, a typed nil != nil
}
func TestFailedAssertMessage(t *testing.T) {
type chicken struct{}
type egg struct{}
st.Assert(t, egg{}, chicken{})
}
func TestFailedRefuteMessage(t *testing.T) {
st.Reject(t, 42, 7*6)
}
func TestFailedTableMessages(t *testing.T) {
table := []struct{ val int }{
{0}, {1}, {2},
}
// Continues if expectation fails
for i, example := range table {
st.Expect(t, example.val, 1, i)
}
// Stops when first assertion fails
for _, example := range table {
st.Assert(t, example.val, 1)
}
}
func TestDeeperEquality(t *testing.T) {
type testStr string
slice1 := []interface{}{"A", 1, []byte("steak sauce")}
slice2 := []interface{}{"R", 2, 'd', int64(2)}
map1 := map[string]string{"clever": "crafty", "modest": "prim"}
map2 := map[string]string{"silk": "scarf", "wool": "sweater"}
str1 := "same"
str2 := testStr("same")
st.Expect(t, slice1, slice2)
st.Reject(t, slice1, slice1)
st.Expect(t, map1, map2)
st.Reject(t, map1, map1)
st.Expect(t, str1, str2)
st.Reject(t, str1, str1)
}
